Astruc, Arnaud. "Fluoration catalytique de chloropyridines en présence de fluorure d'hydrogène et de fluorures métalliques." Thesis, Poitiers, 2015. http://www.theses.fr/2015POIT2314/document.
Full textThe production of fluorinated aromatic synthons, used as building-blocks for the synthesis of more elaborated molecules for therapeutic and phytosanitary goals, has been increased since past years. Besides, only few catalytic fluorination reactions by Cl/F exchange in gas phase are developed for the preparation of these synthons. However, these reactions are cheaper and more environmentally friendly than conventional organic chemistry processes.The feasibility of this reaction was established in this work for the fluorination of 2-chloropyridine (as a simple model molecule) into 2-fluoropyridine, with a solid catalyst (metal fluoride) and HF at 300°C. Various metal fluorides (LaF3, MgF2, SrF2, CaF2, BaF2, Ba1-xLaxF2+x, AlF3, fluorinated Cr2O3) with significant specific surface areas under HF atmosphere and tunable acid properties, was firstly prepared. The catalytic test carried out on 2-chloropyridine allow us to point out a correlation between strength of Lewis acidity of catalysts and their catalytic performances and to propose a reaction mechanism. Cl/F exchange is promoted by catalysts with weak strength of acidity and particularly those containing barium.Eventually, the reaction was generalized to the fluorination of other substituted chloropyridines in order to determine the reactivity according to the position of the chlorine atom on the pyridine ring and the influence of electron withdrawing groups (-Cl, -CF3). Ortho positions are always the most reactive. Whereas meta positions remain completely inactive, it is possible to activate the para position under more drastic conditions

Full textThe synthesis of yttrium fluoride nanoparticles within reverse microemulsions produces monodisperse population of single crystals of well-defined size and with an octahedral shape. The main advantage of yttrium fluoride is that it can be doped, without loss of crystal structure, in order to confer dopant’s intrinsic properties. Adding a shell of lanthanide fluoride is also possible. Furthermore, the synthesis of nanoparticles for the medical imaging allows to increase the sensor’s sensibility since they contain more active ions then their organic equivalents which, often, contain only one. As part of this project, the lanthanide used as a dopant or to make a shell is gadolinium. Thus, relaxometric properties of different types of nanoparticles, synthetized by the single reverse microemulsion method, are measured and compared. Addition of a silica shell is made in order to increase the colloidal stability of aqueous suspension. Keywords: Gadolinium fluoride, Micelles, Nanoparticles, Reversed microemulsion, Silica shell, Yttrium fluorire.

Full textSolid-state fluoride-ion batteries rely on the reversible exchange of the F- ion between a metal and a metal fluoride through a solid electrolyte. These electrochemical devices can theoretically reach energy densities superior to conventional Li-ion commercial batteries. Consequently, fluoride-ion batteries can be seen as a new promising chemistry generating a growing interest. In this context, a part of our work has been dedicated to the development of a cell allowing the evaluation of their electrochemical performance. Moreover, particular attention was given to the electrochemical properties of the solid electrolyte, BaF2-doped LaF3, La1-xBaxF3-x. Finally, the structural changes taking place at the electrodes upon charge/discharge were studied in order to gain insight into the electrochemical mechanisms involved in these devices

Full textPour cela, nous avons cherché :
* à déterminer le rôle de ces ions sur le diagramme de phases CaO-SO3-H20 à température ambiante ;
* à déterminer l'effet de la température (simulation de la cuisson de gypse en plâtre) sur ce diagramme de phases ;
* à comprendre la différence de réactivité entre les différents échantillons après cuisson.
Les ions HPO42- et FPO32- peuvent se substituer aux ions sulfates et entraînent une cristallisation du gypse avec une morphologie en "roses des sables". Lorsque la totalité des ions sulfates est substituée par les ions HPO42- (ou FPO32-), de nouvelles phases apparaissent : l'ardéalite (Ca(SO4)1-x(HPO4)x.2H2O avec 0.42< x < 0.54 puis la brushite : CaHPO4.2H2O (ou le fluorophosphate de calcium dihydraté : CaFPO3.2H2O). La déshydratation des phases pures (brushite et fluorophosphate de calcium dihydraté) et solutions solides a été étudiée. Nous avons retenu que lors de la calcination de la brushite à 150°C, il n'y a ni déshydratation totale, ni passage par une phase sous-hydratée mais obtention d'un mélange de deux phases : la brushite (24%) et la monétite (76%) ayant des propriétés différentes de la brushite et de la monétite seules. A cette même température, la déshydratation du fluorophosphate de calcium dihydraté provoque un dégagement d'acide fluorhydrique (gaz responsable de la corrosion prématurée des fours) et de l'apparition d'une phase de phosphate de calcium amorphe. La réactivité de nos échantillons après calcination (sous forme de plâtre) a pu être interprétée à partir des résultats obtenus par couplage de la conductimétrie avec la pH-métrie et ponctuellement des mesures d'extraction de solution et analyse du solide résiduel au cours de l'hydratation. Nous avons pu conclure que :
- les ions HPO42− syncristallisées ou appartenant aux produits de déshydratation de la brushite (soit un mélange brushite et monétite) entraînent un retard à l'hydratation (ce retard est maximal pour une température de calcination de la brushite à 160°C). Ces retards sont accentués si l'on opère en milieu alcalin. (Ainsi, les traitements de neutralisation à la chaux des phosphogypses contenant des impuretés phosphatées sont néfastes pour lhydratation).
- les ions FPO32− appartenant à la phase fluorophosphate de calcium augmentent la durée d'hydratation, mais syncristallisés, ils accélèrent les temps de prise s'ils sont issus d'une cuisson "flash", ou bien se transforment en ions HPO42− syncristallisés (avec dégagement d'acide fluorhydrique) pour un mode de calcination plus lent et lon est alors ramené au cas précédent. Ces travaux de thèse ont donc permis de mettre en place des méthodes de caractérisation des phosphogypses, de comprendre certains phénomènes observés en usines telles que des fins de prise très longues, la corrosion rapide des fours, et d'établir un classement pour connaître leur aptitude à une valorisation dans l'industrie plâtrière.

Full textStarting from the synthesis of fifteen different types of inorganic nanocrystals, the general trends of metal fluoride nanocrystals have been successfully unravelled. Using the co-precipitation method, we reported the easy, fast and reproducible synthesis of LnF3 nanocrystals and the detailed mechanistic studies of different synthetic conditions. Through the complete study of the surface chemistry, a new kind of ionic self-assembly in colloidal systems has been proposed. Using experimental techniques and molecular dynamics simulations, we postulated this self-assembly mechanism not only specific for the studied case but also applicable to other kind of systems. In addition, thermodynamically stable patchy nanocrystals have been also obtained using an easy, fast and reproducible method. The behaviour of these patchy nanocrystals has been investigated in detail using this dual approximation, from experimental techniques to all-atomistic molecular dynamics simulations. Our results revealed the spontaneous and selective attachment of cations and anions in their different exposed faces, as well as, selective solvent interactions. Going one step further in patchy nanocrystals, we demonstrated that the different facets of the obtained nanocrystals can be modified selectively. Cations and anions can be removed from nanocrystal surface via the addition of a new molecule containing an amino group or a carboxylate respectively. Likewise, using a zwitterionic molecule, the homogenisation of the surface was possible releasing at same time cations and anions. Additionally, some growing process were carried out to enhance the obtained particles, allowing bigger hexagonal-faceted nanocrystals while trying to modify the organic stabilisers. In addition, EGA-MS technique has been tested to simplify the complex pathway to full-characterise colloidal systems. We demonstrated that using a simple experimental technique, the full characterisation of a colloidal system is possible, comparing the results with our previous characterisations. This thesis is mainly based on the mechanistic understanding of the synthesis and the final behaviour of the surface of LnF3 nanocrystals. In consequence, this knowledge will allow the control and manipulation of the bridge between synthesis and applications, currently called surface chemistry. Finally, some initial applications will be presented as different pathways emerged from the manipulation of the unravelled systems, being promising candidates for material science and medical fields.

Full textFerroelectric ceramics with general formula Pb(ZrxTi1-x)O3) (PZT) are intensively used in many industrial domains like medecine or aeronautics owing to their dielectric and electromechanical properties. The aim of the study is the search of hard PZT ceramics with stable and reproductible characteristics versus temperature and under mechanical uniaxial stress. A non hysteretic behaviour versus both types of sollicitations is also needed. These specificities are required for strongly spinned devices like vibratory gyroscopes in which ceramics undergo large mechanical stresses. Besides, the material must exhibit low dielectric constant and high mechanical quality factor. In order to reach these objectives, new Fluorine-doped PZT materials have been prepared by a wet method and characterized. The partial fluorine - oxygen substitution has been realized on a nominal composition Pb0. 89(Ba, Sr)0. 11(ZrxTi1-x)O3 doped with magnesium

Full textDiazoketones are valuable intermediates in organic synthesis and the elaboration of α-diazocarbonyl scaffolds has aroused a steady interest for many years. The terminal diazoketones can be added to aldehydes under basic conditions to produce beta-hydroxy-alpha-diazoketone compounds with a high synthetic potential. In this context, our project aimed at promoting this type of reaction under mild conditions without using a base. The strategy adopted was based on the use of α-trialkylsilyl-α-diazoacetones and their specific nucleophilic activation by a fluoride ion. Initially, the synthesis of α-trialkylsilyl-α-diazoacetone was optimized and then, an extensive study of the reaction parameters allowed the development of an efficient aldolisation of TES-diazoacetone induced by TBAF. The nucleophilic, weakly basic conditions employed tolerate a wide range of substrates and constitute a practical high-yielding experimental procedure. The asymmetric extension of this methodology was then studied by using a chiral ammonium fluoride derived from Cinchona alkaloid. The condition set up allowed to elaborate the first enantioenriched beta-hydroxy-alpha-diazoacetones (e.e = 35%) in high yields. Finally, this methodology was successfully extended to TIPS-diazoacetone. The robustness of the TIPS protective group makes it possible to envision a range of synthetic « methyl-side » transformations without desilylation of the azomethine position of the diazo-aldol. This study paves the way for future exploration of the reactivity of TIPS diazoaldols

Full textMolten fluorides are used in Molten Salt Reactors MSR such as the non moderated fast reactor MSFR, where the molten salt LiF-ThF4 is the fuel and the coolant. The formation of fission products (FP) such as lanthanides, during the reactor operation, possibly modifies the physicochemical properties of the melt. It is therefore important to characterize the melt from the structural and the dynamics point of view in order to determine its properties. Because of problems related to the radioactivity of thorium, as well as requirements related to spectroscopic methods, the system studied in this thesis is the LiF-ZrF4-LaF3 (zirconium and lanthanum are possible FP). The approach followed in this thesis combines measurements by NMR spectroscopy and EXAFS at 850 °C with molecular dynamics simulations. In the molten salt, we have shown the existence of zirconium and lanthanum complexes with different coordination numbers, whose proportions depend on the composition. Depending on the content of ZrF4, [ZrF7]3- species are dominant but change slightly and are further connected between each other’s via bridging fluorine. The addition of LaF3 to the mixture stabilizes the 7 coordination number around the zirconium and tends to enrich the environment of lanthanum with fluorides. A medium-range order is established between the various complexes containing zirconium and lanthanum due to bridging fluorine. Species dynamics is slower when the amount of either ZrF4 or LaF3 is higher. We noted a significant effect on the structure and dynamics of species starting 10 mol%. LaF3 added to the medium. The data obtained by this novel approach concerning the chemistry of the molten salt in MSR containing FP, are fundamental to improve the separation of these products and optimize the process

Full textThe aim of this thesis is to support the trends of the chemical industry development that promote sustainability. The goal is an integrated pollution control to reduce the emissions in order to promote sustainable production activities.In this sense, the common methods for fluoride removal from industrial wastewater involve chemical precipitation. The process generates large amounts of a water rich sludge requiring disposal with increasing costs. Due to the high water content and the low quality of the sludge, reuse of fluoride is not an economical option. The removal of fluoride in a fluidized bed reactor by crystallization has been presented in this thesis as an alternative to the chemical precipitation. When it is compared with the conventional precipitation process, the major advantage of this new clean technology is the elimination of sludge formation, the materials recovery and the reduction of solid waste.

Full textZeolites have wide applications in chemical and petrochemical industry as catalysts and sorbents due to their regular channels and cavities with sizes below 2 nm, large surface areas, strong acidity, and shape selectivity. The downside however, is that the sorption and catalytic performance of zeolites is often compromised due to the fact that the reactants and products may face severe intra-pore diffusion limitations. Consequently, a variety of approaches have been designed in order to lower these diffusion restrictions and improve the performance of zeolites. The most commonly used approaches are decreasing the particle size of zeolite crystals, and the introduction of a secondary network of large pores (mesopores) connected to the native micropores. In the present study, we show how the controlled fluoride etching leads to a clear understanding of the intrinsic structural properties of mordenite zeolite crystals, and the central role of crystal structure in developing advanced hierarchical materials. The dealkylation of 1,3,5 Triisopropylbenzene is selected to highlight the catalytic effects of fluoride etching on the mordenite zeolite and specifically on its external surface. In addition, fluoride etching on zeolite L and beta were carried out. We evaluated the catalytic performance of zeolite beta and its corresponding hierarchical beta treated with NH4F in terms of conversion capacity, and life time at high conversions of Methanol-to-Olefins
