▼ The work presented in this thesis is aimed to design efficient reactive crystallization operations that could potentially be implemented in the manufacture of enantiomerically pure compounds and β-lactam antibiotics. Multiple aspects of solution thermodynamics, reaction engineering and crystallization from complex solutions are involved and will be discussed in detail through the following chapters. The first piece of this work utilizes reactive crystallization for the manufacture of enantiomerically pure amino acids. Chemo-enzymatic stereoiversion reactions are used to enrich saturated or supersaturated solutions to favor the selection of a desired enantiomer. L-Methionine and L-Phenylalanine were resolve successfully from racemic mixtures by cyclic stereoinversion. r D-amino acids were oxidized by D-amino acid oxidase (D-AAO) and the resulting ketoacid was subsequently reduced by ammonia borane producing a racemic-mixture After the necessary enantiomeric enrichment was reached, system conditions were changed to induce supersaturation and promote crystal formation. In each case crystals with chemical and enantiomeric purities greater than 99% wt. were recovered. experimental information about reaction and crystallization kinetics was used to developed models. Such models were used to design model-based optimizations in which the productivity of the operation was enhanced by selecting an optimal temperature profile. The second example is a reactive crystallization towards the manufacture of β-lactam antibiotics. One of the major drawbacks of the utilization of enzymes towards the manufacture of β-lactam antibiotics is the fact that the same enzyme that catalyzes the synthesis of the antibiotic also catalyzes its hydrolysis and thus, its degradation. The reaction scheme is a kinetically controlled synthesis in which the desired product is an intermediate within the network. Hence, the focus of this work is to design an efficient reactive crystallization in which the product is crystallized before it is consumed by hydrolysis. In order to accomplish this goal we have study solution equilibria, reaction kinetics, and crystallization kinetics. Even though crystallization kinetics of ampicillin has been previously reported; the reported models are not applicable to a reactive crystallization scheme for a variety of reasons. In this work, we have developed a robust model that can be applied to multiple crystallization protocols that are consistent with the conditions at which the enzymatic reaction can be performed. Finally, a reactive-crystallization scheme in which ampicillin was successfully recovered from solution was developed. In this work, crystal seeds were used to promote crystallization of the desired product from the complex media. The results indicated that is possible to perform the reaction and crystallization in parallel, and still recover crystals with high purity. This work is the first example in which ampicillin was produced and recovered with high purity in a single stage. Previous work on… Advisors/Committee Members: Rousseau, Ronald W.

▼ The particle size or crystal size distribution (PSD or CSD) of a solid product from a crystallizer is important in handling the solid. CSD related properties might be improved with larger particle size. The principle of particle size increase in continuous crystallization processes is to remove fine particles at a faster rate than large ones. Two technologies based on this principle are the Double Draw-Off (DDO) and the Fines Dissolving (FD) crystallizer configurations. Design charts were developed for the Fines Dissolving crystallizer. It was found that the particle size increase passes through a maximum value as the fines classification cut size is increased. Based on this information a design protocol was suggested for the FD crystallizer. A limited amount of data are required for this method of design. The modified DDO crystallizer configuration was developed in order to obtain particle size increase in processes with high natural slurry density for which a build-up of solid is impractical. This involved a recycle of a part of the overflow (in DDO operation) after further classification of particles to remove fines in a size range L(F1) to L(F2), thus controling the slurry density in the crystallizer. Design equations and design charts for this configuration were developed. Analysis showed that a stream with some fines in it might be more effective in decreasing the slurry density than a clear filtered liquor. Particle size increase was demonstrated for sodium chloride crystallization in caustic liquor using the FD, DDO and modified DDO crystallizers. A fines/feed flow modification as well as actual fines dissolution was used in the FD experiments. Significant size increase was observed in both cases. These experiments indicated that appreciable dissolution cost would be involved in FD operation. The DDO experiments produced large crystal particles with associated increase in slurry density. Slurry density information from large scale operations indicated that DDO operation would be possible for DDO ratios upto about 2.5. The modified DDO configuration also produced larger particles. However, size increases were less than expected. Loss of supersaturation outside the crystallizer might be the reason. Appreciable reduction of crystallizer vessel fouling was observed in the DDO and modified DDO experiments. Randolph et al. (1990) demonstrated significant particle size increase for calcium sulfite precipitation in flue gas desulfurization (FGD) liquor using a DDO crystallizer. Experimental particle sizes were appreciably larger than predicted values. A partial fines dissolving model was proposed to explain this behavior. It was shown that dissolution of particles smaller than 8 μm in only about 2.8% of the recycle stream was enough for the additional size increase.

▼ The triterpene Oleanolic Acid (C₃₀H₄₈O₃) OA-H which has poor aqueous solubility crystallizes from various organic solvents, particularly alcohols, to give solvate co-crystals. Chapter 2 describes the preparation of a number of these solvates and their characterization by pXRD and SXRD. The control of the formation of solvated versus anhydrous phases are also discussed and appears to be controlled by the initial temperature of crystallization, with lower temperatures favoring solvates. A predicted unit cell from powder diffraction data is discussed for the oleanolic acid anhydrous phase, for which a single-crystal is difficult to obtain. In Chapter 3, the ability of oleanolic acid to form salts with various amines and its potential as a chiral resolving agent via the formation of diastereomeric salts is explored. Oleanolic acid is a chiral acid and thus it may be able to resolve racemic organic bases, hence it can be a potential resolving agent for cations. Various racemic amines were used to study the effectiveness of oleanolic acid as a resolving agent for cations. In our investigation, we discovered that oleanolic acid forms a hydrated salt when recrystallized with S-2-methylpiperidine. However, there occurs some H/Me disorder of the amine and both R- and S-isomers are incorporated in the same crystal. Thus, the S-isomer is resolved with only 50% enantiomeric excess. Whilst the 2-methylpiperidine is not well resolved, its stereoisomer – 3-methylpiperidine was also recrystallized with oleanolic acid to resolve the S-isomer, with almost 100% enantiomeric excess. Furthermore, the amine s-butylamine was also successfully resolved using oleanolic acid as a chiral resolving agent. Therefore, our studies demonstrate the great potential for oleanolic acid as a low-cost, efficient chiral resolving agent via the formation of diastereomeric salts. The use of oleanolic acid as a resolving agent is not limited to diastereomeric salt formation. Chapter 4 investigates the potential for oleanolic acid as a chiral resolving agent via the formation of co-crystals with neutral molecules. In particular, we investigate the ability of oleanolic acid to resolve chiral alcohols via cocrystallization of solvated phases, owing to oleanolic acid’s ability to form solvated phases as demonstrated in Chapter 2. Oleanolic acid was found to partially resolve (2R, 3R) 2,3-butanediol by forming a co-crystal phase whilst oleanolic acid sodium salts were able to partially resolve s-butanol. Given the potential of oleanolic acid for various applications and the importance of molecular perturbation on structural chemistry, the studies conducted in chapters 2, 3 and 4 are then expanded to oleanolic acid synthetic derivatives and similar triterpenes, ursolic acid and glycyrrhetinic acid, in Chapter 5 to study the differences in structure and crystallization that may occur when slight changes are made to the oleanolic acid structure. It was discovered that oleanolic acid derivatives appear to crystallize in different…

▼ The knowledge of three-dimensional structures of membrane proteins aids in structure-based drug design, since about 60% of approved drug targets are known as membrane proteins. To date, chaperone-assisted protein co-crystallization that bypass the need for animal immunization is becoming an attractive method to elucidate structures of recalcitrant targets such as proteins with intrinsically disordered domains as found in membrane proteins. Here we describe antibody-engineering strategies for developing crystallization chaperones. Toward this goal, we (1) engineered EE peptide-specific single-chain variable fragment (scFv) to improve biophysical characteristics, (2) constructed synthetic single domain antibody library to be specific for targets by phage display, and (3) de novo designed FLAG peptide-specific antibodies using a novel computational method. In the first study, we converted peptide-specific scFv to antigen-binding fragment (Fab), which is the most successful format of antibody-based crystallization chaperones for integral membrane proteins so far. The larger size of Fab/EE increased the overall stability without disruption of binding affinity and extended crystal contact areas those are favorable characteristics for use as a crystal chaperone. In the second study, a 10⁶ synthetic phage display single domain antibody (sdAb) library was constructed and used to identify sdAbs binding the repeat in toxin domain of B.pertussis adenylate cyclase toxin (ACT). This protein is an intrinsically disordered calcium binding protein with no homology to any known protein structure and is a candidate vaccine antigen. From phage-based screening, we isolated three sdAbs to be used for further characterization. In the last study, we utilized an in silico approach to the design the antibodies using OptCDR that is a general computational method that employs de novo design of complementarity determining regions (CDRs) to engineer antibody-antigen interactions. Using this method, we designed CDRs binding the minimal FLAG peptide (sequence: DYKD) and isolated four antibodies with high specificity and nanomolar affinity for the DYKD. The result demonstrates that antibody specificity based on in silico design method can guide future engineering of antibody-based crystallization chaperone. Taken together, we have identified antibodies with improved binding properties and biophysical characteristics for using as crystallization chaperones without animal immunization to help guide future antibody chaperone engineering for the structural investigation of diverse target proteins.

▼ In this work I present both a phenomenological and fundamental study of the crystallization of the organic-inorganic halide perovskites; this includes determining the overall structural evolution, extraction of kinetic parameters for the primary crystallization step, and establishing several processing-structure relationships. In addition, I will show examples of the application of the primary results to control crystal growth and enhance the material's performance in working devices. The organic-inorganic halide perovskites have shown great promise as a potential next generation photovoltaic (PV) material with device efficiencies exceeding 17%. For the last 2-3 years most research efforts have been dedicated to understanding the general operating principles of perovskite PV devices and engineering better device architectures. Although these efforts have resulted in an unprecedented increase in efficiencies over a very short period of time, many reports point to film or crystal morphology as a limiting factor. In order to control film and crystal growth a better understanding of this systems fundamental crystallization behavior is needed. Employing in-situ wide angle X-ray scattering allowed for the determination of the general evolution of thin films cast from solution. This initial work revealed an Ostwald Step Rule path in which the final perovskite is preceded by a solid-state precursor structure. Understanding the general evolution allowed for monitoring of the precursor-perovskite transition to establish processing-structure relationships. One such relationship is the temperature profile used in the annealing step, optimization of this profile results in better film coverage and better crystal texture, both of which increase device performance. The second major study was to elucidate the disposition of the constituent salts during crystallization and confirmed that all reagent salts are completely dissociated during film formation. This result led to the realization that the crystallization was insensitive to the lead source allowing for manipulation of the system kinetics by using alternate lead compounds. Finally, a study of the kinetics of the precursor-perovskite transition provided for the extraction of the activation energy. Combined with the previous work, the kinetics study gave the insights needed to determine a general formula for the precursor structure as well as a general pathway for the solid-state transformation. The implication of the work presented here is better control of perovskite thin film growth through manipulation of the processing and chemistry employed. Several recent reports, as well as my own experimental results, are beginning to show the value of this understanding through better films, made at lower temperatures and faster times, and providing improved performance in working PV devices.

▼ The design and operation of current industrial crystallizers is largely based on experience and practiced skills rather than sound understanding of the process. Crystallization equipment is selected from a number of state-of-art industrial crystallizers followed by optimization for that particular type of equipment. Various physical phenomena which are strongly entangled occur in these crystallizers. The current equipment-based design and optimization of crystallizers causes a lack of control over these physical phenomena. Within the TU Delft Process and Energy department, the development of a task-based design strategy has been initiated in order to obtain better control over the physical events governing the crystallizer product quality. This task-based design is a phenomena-based approach in which fundamental building blocks representing a physical process are used for design. A task based design library model was developed in gPROMS which can be applied to a wide range of crystallization processes concerning the nature of the chemical system, operation mode, flowsheet configuration and crystallizer type. However, the crystallization method is solely based on cooling crystallization. In this thesis research, the task-based design tool is extended with the crystallization method of 'membrane distillation-assisted crystallization'. The main objective was the development of a predictive model for membrane distillation-assisted crystallization with a focus on the process performance. The employed membrane distillation configuration is a 'sweeping gas membrane distillation' arrangement. A mathematical model is developed in gPROMS for the sweeping gas membrane distillation module, followed by validation with experimental obtained data. Validation of the sweeping gas membrane distillation model shows that the model results are adequate. A sensitivity analysis has been performed and compared to literature to obtain more knowledge about the performance of the employed sweeping gas membrane distillation module for this thesis. Subsequently, the sweeping gas membrane distillation model is integrated in the task-based design model library in order to develop the superstructure of membrane distillation-assisted crystallization. The developed superstructure has been validated as well with experimental obtained data in which comes forward that the membrane distillation-crystallization model performs as intended. As the membrane distillation-crystallization model performs adequately, it can be used as a predictive model tool. Since membrane distillation-assisted crystallization is a relatively new concept, case studies were performed in order to gain more insight in the process. In the case studies the membrane distillation-assisted crystallization model was performed under different circumstances. The results from the case studies can be used to aid in design and optimization of new experiments. Based on the findings of the validation procedures, sensitivity analysis and case studies, it can be concluded that the membrane… Advisors/Committee Members: Kramer, H.J.M., Anisi, F..

▼ Colloidal crystallization in sedimenting systems is an incompletely understood process, where the influence of interparticle forces on the three-dimensional (3-D) microstructure remains to be fully elucidated. This dissertation outlines work that is intended to improve our knowledge of this subject by studying sedimentation equilibrium and phase behavior for electrostatically repulsive systems, as well as the interfacial crystallization of attractive depletion systems. Towards this end, several analytical and experimental tools have been developed to explore the thermodynamic behavior of these systems. For example, the experimental challenges necessitated the development and implementation of the following in this work: (1) core/shell silica particles incorporating molecular fluorophores or semiconductor nanocrystals; (2) modification of silica particle surfaces; (3) the design of specialized sedimentation cells; and (4) the development of a novel fluorescent intensity-based approach to quantifying colloidal sediments. Analysis of the experimental data required the use of the following tools: (1) location of particle centers from images; (2) deconvolution of intensity profiles using a novel Monte Carlo-type algorithm; and (3) prediction of colloidal phase diagrams using perturbation theory. On the basis of this work?s experimental and simulation data, it is concluded that competing orientations of crystal grains may suppress crystallization at grain boundaries, resulting in a non-uniform depth of the fluid/solid transition. Also, it was demonstrated that the grain size in depletion crystals formed from quantum dot-coated silica particles can be increased by localized annealing with the confocal microscope?s laser. Additional findings include the ability of the intensity-based approach to measure interparticle forces in colloidal sediments, as well as the inability to use perturbation theory to predict two-dimensional colloidal fluid/solid transitions. While significant progress has been achieved, work on 3-D imaging of colloidal depletion crystals in a refractive index-match medium is ongoing. This work improves our understanding of 3-D colloidal crystallization at interfaces, as well as provides new tools for future research. Also, this work demonstrates a potential route for zone refining of colloidal crystals, a technique that may be important in the search for low-defect 3-D arrays that can be used as templates for photonic bandgap materials.

▼ Recent work has shown that silicic volcanism can be abundant in intra-oceanic subduction settings, and is often associated with large explosive caldera-forming eruptions. Several major petrogenetic questions arise over the origin and eruption of large amounts of silicic magma at these relatively simple subduction settings. This study has investigated the geochemistry of pyroclasts collected from four volcanoes along the Kermadec arc, a young (<2 Myr) oceanic subduction zone in the southwest Pacific. Raoul, Macauley and a newly discovered volcano (here informally named 'New volcano') in the northern Kermadec arc, and Healy volcano in the southern Kermadec arc have all erupted dacitic to rhyolitic pumice within the last 10 kyr. For Raoul, New volcano and Healy, whole rock major element compositions fall with a limited compositional range. In contrast, pumice dredged from around Macauley caldera covers a wide compositional range indicating that there have been multiple silicic eruptions, not just the Sandy Bay Tephra exposed on Macauley Island. Distinctive crystal populations in both pumice samples and plutonic xenoliths suggest that many of the crystals did not grow in the evolved magmas, but were mixed in from other sources including gabbros and tonalites. Such open system mixing is ubiquitous in magmas from the four Kermadec volcanoes studied here. Silicic magmas, co-eruptive mafic enclaves and previously erupted basalts show sub-parallel REE patterns, and crystal composition and zonation suggests that mafic and silicic magmas have a strong genetic affiliation. Examination of whole rock, glass and mineral chemistry reveals that evolved magmas can be generated at each volcano through 60-75% crystal fractionation of a basaltic parent. These findings are not consistent with silicic magma generation via crustal anatexis, as previously suggested for the Kermadec arc. Although crystallisation is the dominant process driving melt evolution in the Kermadec volcanoes, the magmatic systems are open to contributions from both newly arriving melts and wholly crystalline plutonic bodies. Such processes occur in variable proportions between magma batches, and are largely reflected by small scale chemical variations between eruption units. Larger scale chemical trends reflect the position of the volcanoes along the arc, which in turn may reflect structural changes in the subduction zone and variations in sediment influx.

▼ This thesis reports on the work carried out by the author on the crystallisation kinetics and optical properties of thin amorphous Ge₂Sb₂Te₅ films. This study is prompted by the application of these films in optical phase change recording media. The work is partly theoretical and partly experimental in nature. Starting from the general nucleation and growth theory, it was shown that the Johnson-Mehl-Avrami-Kolmogorov (JMAK) equations are equally valid under linear heating conditions as under isothermal annealing conditions. All peak shift methods for determining the JMAK parameters were shown to be equivalent and valid within the JMAK framework. The crystallisation kinetics of amorphous Ge₂Sb₂Te₅ films were investigated under isothermal annealing conditions. Crystallisation was found to be preceded by a temperature dependent incubation time. The JMAK parameters were determined and found to be in good agreement with the nucleation and growth parameters, which were determined independently. The optical properties of many materials can be described by three parameters: the plasma energy, Ep, an effective transition energy, Δ, and a damping constant, Γ. A theoretical model was developed that aims to calculate these parameters from the co-ordination of nearest neighbours in the structure. The model was found to work for a simplified silicon Hamiltonian and it is described how the model could be extended to include more realistic systems. Ep, Δ and Γ were determined before and after crystallisation of amorphous Ge₂Sb₂Te₅ films. From the numerical values of these parameters, it was concluded that the change in the reflectivity upon crystallisation is primarily due to the change in Δ. The change in the co-ordination of nearest neighbours upon crystallisation was investigated. The topological co-ordination was found to be very similar in both phases. The change in the optical properties is thought to be due to the change in chemical order of the nearest neighbours.

▼ Peptidases play fundamental roles in all living organisms and their dysfunction is associated with a variety of diseases. Although sequences of peptidases encoded in genomes throughout life have become readily available via high throughput sequencing technologies, research on their structural and functional characterizations lags behind due to challenges related to their crystallization and time-intensive biochemical/biophysical studies. Signal Peptide Peptidase (SPP) is an intramembrane aspartyl peptidase that cleaves signal peptides within the hydrophobic region of cellular membrane. SPP plays important roles in cellular functions such as immune system regulation. Structural characterization of membrane proteins including SPP is challenging due to their hydrophobic content which prevents crystallization. Structures of membrane proteins are severely underrepresented: number of unique membrane protein structures is still less than 1% in Protein Data Bank. Here, a new generalizable method was introduced to overcome crystallization challenge of membrane proteins. A toolbox of single chain antibody fragments (scFvs) specific to the EYMPME peptide (EE) epitope was developed for use as co-crystallization chaperones. Structures of all designed scFvs were solved and their crystallization propensities were systematically explored to improve their chaperone abilities. Tight complexation of anti-EE scFvs with EE-tagged SPP and another test membrane protein was demonstrated. Important lessons learned during crystallization and co-crystallization trials of scFvs and SPP are discussed in this dissertation. To understand peptidases at a mechanistic level requires both high resolution structures and extensive structure-function studies in which residues are systematically altered and differences in functionality of the peptidase are measured. Although a low resolution structure of inactive SPP became available during my PhD studies, details on how SPP recognizes and catalyzes its substrate are still not known. Here, preliminary data for a structure-function study to understand substrate gating mechanism of SPP are presented. Finally, structure-function studies of 5-nitroanthralinic acid aminohydrolase (5NAA-A), a metallo-peptidase family member that catalyzes a deamination reaction on a natural, toxic nitroaromatic compound, are presented. 5NAA-A has evolved a function other than peptide hydrolysis but is structurally and evolutionary related to peptidases and is thus classified as a non-peptidase homolog. We characterized 5NAA-A biochemically and biophysically, and obtained snapshots of its mechanism by solving its crystal structures in various states. The 5NAA-A structure and its nucleophilic aromatic substitution mechanism expand our understanding of the great diversity of enzymes capable of transforming natural organic compounds in our ecosystem.

▼ This study investigated water-in-oil (W/O) super-concentrated emulsions used as pumpable explosives. The aqueous phase of the emulsions is a supersaturated nitrate salt solution (at room temperature), with a volume fraction of approximately 0.9. Instability of such emulsions arises either from crystallization of the dispersed phase in the system during ageing or under high shear conditions. Here, we report an alternative approach to stabilize this highly concentrated W/O emulsion by adding colloidal particles in combination with short amphiphilic molecules. Thus, the primary goal of this research concerned a phenomenological study of the dependence of surfactant-to-particle ratio as well as the particle hydrophobicity index on stability under high shear in the emulsification process, rheological properties and stability against initiation of crystallization of an internal phase both with ageing and under high shear with a view to optimize the time to the start of crystallization of the emulsion both with ageing and under high shear; to elucidate the mechanism of initiation of crystallization of an internal phase (homogeneous or heterogeneous) and shed light in the stabilization mechanism of the emulsion; to determine how the emulsion formulation content affect pumping characteristics as measured by characteristic rheological parameters. A series of five fumed silica nanoparticles, each with a different hydrophobicity index (HI) in the range of 0.60 – 3, were used in the form of single types of particles as well as binary mixtures. These particles were combined with a low molecular weight conventional surfactant, Sorbitan MonoOleate (SMO), into the oil phase prior to emulsification. It has been found that regardless of the particle hydrophobicity, fumed nanosilica alone cannot form highly concentrated W/O emulsion up to 90 vol%. Moreover, Pickering emulsions are unstable under shear conditions and thus it is difficult to make highly concentrated W/O pumpable emulsion explosives using only fumed nanosilica. The correlation between the refinement time and SMO-to-particle ratio showed a deflection point/transitional point in the stabilization mechanism. Below the transitional point the silica content dominates over SMO. Conversely, above the transitional point the particles have little effect and the SMO dominates. A thermodynamic consideration revealed that in this region only SMO is likely to adsorb at the W/O interface and controls the emulsifying process. As with refinement time, the correlation between the shear modulus and SMO/particle ratio shows a deflection /transitional point which, as before, mark the transition point between regions of particle or SMO domination. Interestingly, it was found that for each HI, the initiation of crystallization is the most delayed, both on shelf life and under high shear, when the emulsion is prepared with an SMO-to-particle ratio equaling exactly the value at this transitional point. Moreover, the research demonstrated that a drastic change in mechanism of initiation of…

▼ Crystallization has been widely used for product separation and purification in the chemical, pharmaceutical and food industry because it can separate one or more components from a liquid mixture in pure solid form. However, to obtain these components with desired attributes has remained a challenge, owing to the difficulties in understanding the crystallization thermodynamics and kinetics of the system under consideration, as well as in utilizing such information for process development and synthesis. Compounded by the persistent pressure to meet the ever-changing market demand, developing systematic methods that can facilitate the synthesis of crystallization-based processes for producing crystals of required qualities are thus of practical significance. In this research, we achieve this goal by developing methods that rely on solid-liquid equilibrium (SLE) phase diagrams and workflow application to tackle problems in crystallization thermodynamics and kinetics. Three different projects are used to illustrate the important role of SLE phase diagrams on understanding crystallization processes and how phase diagram-aided process synthesis can effectively lead to the separation of crystals of targeted component(s). The focus of the first project is placed on the determination of thermodynamic data of a simplified multicomponent salt lake system, which comprises Li+, Na+, K+, Mg2+//Cl-, SO42- - H2O at 25°C and 1 atm. A method integrating three interrelated activities - representation of phase behavior as a phase diagram/thermodynamic model, experimental measurement of necessary SLE data, and visualization of high-dimensional phase diagrams - is presented to show how solid-liquid phase behavior data salient for process synthesis can be obtained in a systematic and objective-oriented manner. Application of the resulting phase diagram to synthesize a recovery process for salts of high lithium content is also briefly discussed. The second project demonstrates the course of developing a crystallization-based process that can simultaneously separate high-purity C60 and C70 solids from a fullerene mixture with the scientific information obtained from the ternary phase diagram of C60, C70 and o-xylene. The practicability of such a process is verified by a batch experiment, in which C60 and C70 fullerene solids of purity greater than 99 wt% can be produced from a commercially-available fullerene mixture that is pretreated with adsorption to remove higher fullerenes. In the third project, we design and build up a bench-scale prototype of a novel apparatus, namely, evaporative column crystallizer, and demonstrate its feasibility in separating C60-rich solid solution into a solid phase of high purity of C60 and a liquid phase enriched with C70 using the solvent o-xylene under semi-batch operations. The effect of solvent feed rate on the results of separation is investigated and the SLE phase diagram of C60, C70 and o-xylene is used to explain the change in the experimental results. In addition to chemical identity, the product…

▼ This study has been undertaken for two main purposes:- (1)To obtain factual information concerning the rate of growth of sucrose crystals; and (2)To secure some understanding of the operating mechanism of factors influencing crystal growth. Chapter 3 records details of the experimental method used and data gathered for actual growth rates. Associated with these in chapter 2 is set down information believed to have a significant bearing on the mechanism study. For the mechanism study growth has been looked upon as a physical rate process bearing certain analogies to chemical reactions and mathematical treatment has been carried out with this in mind, it being effectively a kinetic study in an essentially physical system. Chemical kinetics has to do with the study of rates of chemical reactions and of the influence of conditions upon these rates. The most important experimental conditions are concentrations (or pressures) of reacting substances, temperature, presence of a catalyst and radiation. In the case of sucrose crystallization the chemical reaction theory is transferred to the physical rate process. The kinetics of sucrose crystallization thus concerns the rate of crystallization of sucrose and the influence of conditions such as concentrations, temperature and impurities. Crystallization is a process in which the solute molecules move from the solution to the surface of the growing crystal and incorporate themselves into the crystal lattice. The relative influence of the crystal surface and mother liquor may then be examined in the light of rate process kinetics. The Arrhenius equation, which is the basis of kinetic studies, for chemical reactions may be stated, k = A e-E/RT where k is the velocity constant in the chemical reaction. In the current studies k is used in this equation as the velocity of crystallization of sucrose and is essentially the physical rate constant of concern in this system. A plot of log k v. 1/T is linear and the activation energy of crystallization (E) may be calculated from the slope of the line. The constant A in the Arrhenius relationship is essentially a frequency factor in chemically reacting systems and its study has been suitably incorporated in the activated complex theory of reaction rates. While some possible analogies are recognised, the full implications are not insisted upon in the present studies. The crystallization of sucrose consists of two consecutive stages, firstly, nuclei formation; and secondly, crystal growth. These current studies are essentially concerned with the latter growth process only. When studying chemically reacting systems, the chemical potential or driving force is the difference between the concentration of reacting material on the one hand and the concentration of the product on the other. In the system of crystallizing sucrose, the driving force is the difference between the concentration of the oversaturated solution and that of a saturated solution. In this thesis supersaturation (S) is defined as the ratio of the…

Note:

This thesis presents the classical model for the kinetics of crystallization of polymers with lamellar morphology. The lamellar thickness and the crystal growth rate are obtained, giving results in agreement with available experimental data. However, the model predicts a divergence of the lamellar thickness at a critical temperature of formation. Point's model, which explicitly considers the segmental nature of the polymer chain, and a finite probability of folding at each stage of the deposition of a secondary nucleus, is then shown to remove this divergence. After detailed consideration of some aspects of this model, the thesis proceeds to a study of the influence of topological constraints (knots) on the kinetics of crystallization of polymer chains. It is assumed that the folding of a chain at a given site can occur if and only if there is a knot. This predicts a lamellar thickness in good agreement with the experimental data corresponding to the polyethylene.

On décrit t ici le modèle classique de cinétique de cristallisation des polymères à morphologie lamellaire. Ce modèle mène à la détermination de l'épaisseur des lamelles cristallines et du taux de croissance du cristal.Ces résultats sont en accord satisfaisant avec les données expérimentales. Cependant, la théorie classique prédit une divergence de l'épaisseur lamellaire à une température critique de formation. 011 présente ensuitela version améliorée de la théorie classique qui mène à une épaisseur lamellaire finie pour toute température de formation du cristal (Point). Dans ce dernier modèle, on suppose un mode de déposition segmentaire de chaque portion des germes secondaires; on suppose également une probabilité finie de pli de la chaine polymérique à chaque déposition segmentaire. Après avoir détaillé certains aspects de ce modèle, on examine l’influence des contraintes topologiques (noeuds) dans les chaines sur leur cinétique de cristallisation. Supposant qu’il y a pli des chaines si et seulement s’il y a noeud à Un site donné, on trouve une épaisseur lamellaire en bon accord avec les résultats expérimentaux pour le polyéthylène.
