A sustainable supply of lithium is essential for the development of modern electrical devices. These devices are based on lithium-ion batteries (LIB), the key element of these LIB is lithium. Recycling is a strategic axis on which the supply of lithium is based in an environmentally and economically sustainable manner. In this context, during this thesis project, our efforts were directed towards the study of lithium recycling by liquid-liquid extraction (LLE). Ionic liquids (ILs) have been used to replace toxic organic solvents. The present work has two practical and theoretical objectives: (i) the development of a new LLE system for the extraction of lithium by combining extractant and IL and (ii) the understanding of the mechanisms of lithium extraction from aqueous media (acids and bases) in an IL medium with different types of extractants (neutrals and acids). Our results showed that it is relatively difficult to design a LLE system capable of directly extracting lithium from a LIB leachate. For this reason, we proposed to extract lithium at alkaline pH, where most of the cations present in the leachate are already removed. The optimal extraction system under these conditions is that using β-diketone in LI. We have demonstrated that this extraction solvent meets most of the requirements of an ideal system for lithium extraction involving IL

Modern chemistry needs to develop new eco-friendly processes, in order to lower wastes and byproducts and avoid the use of toxic reagents. In this context, we focused on a new class of solvents which may satisfy these criterions: ionic liquids (IL) and its use in organic electrosynthesis. We have made a physicochemical study to put in light their strength and weakness in electrosynthetic applications. The high viscosity and a medium conductivity are two brakes for the aimed applications. We propose to optimize these two key parameters by a moderate heating of the solution and the addition of a small amount of a cosolvent. Then, we have tested two types of electrochemical reactions in ionic liquids. In oxidation, the Tempo catalysed oxidation of alcohol to corresponding carbonyl compound was successfully adapted in IL and results are as good as in molecular solvents. We also give information on the mechanism, especially on the pH influence on the kinetics and recycling of the catalyst. In reduction, the reaction is the coupling reaction between a benzylic chloride and an acylating reagent, catalysed with nickel complexes, to form benzylketones. The results, a bit lower in IL than in molecular solvents, shows that IL are also adapted for these reactions combining electrochemistry and homogeneous catalysis with transition metals

The objective of this thesis is to develop a membraneless redox-flow microbattery using ionic liquids (ILs) as electrolytes. Due to their properties, they are well suited for applications related to energy storage. However, they are very sensitive to moisture, expensive, difficult to synthesize and viscous, making their use at an industrial level difficult. A way of overcoming these drawbacks is to mix the IL with a molecular solvent. In this work, we have studied the electrochemical properties of two aprotic and hydrophobic ILs belonging to 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide family and a protic and hydrophilic IL, ethylammonium nitrate (EAN). We have also studied the influence of molecular solvent (γ-butyrolactone, GBL) addition on the physicochemical properties of the mixtures. Physicochemical properties of two eutectic mixtures: ethaline and Menthol-based DES were investigated in order to compare them with an IL commonly used in electrochemical applications. Electrochemical properties of these ILs and their mixtures with GBL had been studied in the presence of different redox couples in order to select two couples to be tested in a microfluidic cell. Electrical characterizations of different membraneless redox-flow batteries have been carried out using these electrolytic media and electroactive species

The liquid-liquid extraction is one of the most studied and developed hydrometallurgical processes, particularly in the areas of applications for the extraction and purification of metals of great interest in the sectors of energy and advanced technologies, such as lanthanides and actinides. Many extractants have been developed for the extraction of these metals in the recent decades where the nature, the arrangement, the rigidity and the stereochemistry of chelating sites determine the affinity and selectivity toward the target metals. The study of chelating systems organized on macrocycles has constituted, in particular, the subject of numerous research studies.In this study, the organization of diglycolamide (DGA) and diamide (DA) subunits on Calix-[4]-arene and resorcinarene cavitand was studied for the extraction of rare earth elements (REEs) and uranium (U). A detailed study on the effect of the organization of DGA subunit on the extraction performance of lanthanides, in toluene, showed that the synthesized macrocycles are more efficient and more selective toward heavy rare earths (HREEs) than the light ones (LREEs). A comparative study for the extraction of lanthanides by these macrocycles in ionic liquid medium revealed that the calix-[4]-arene is a better candidate as preorganised platform than the resorcinarene cavitand. Moreover, a detailed study on the chelating capacity of a calixarene functionalized with diamides (DA) was done for the selective extraction of uranium in sulfuric medium, demonstrating that the diamide pattern is more efficient and more selective than its calixarene analogue

Synthesis and characterization of two new cholinium-based ionic liquids, named N-(2-hidroxyethyl)-N,N-dimethyl-N-octylammonium bis(trifluoromethanesulfonyl)imide [C8linCol]+[NTf2]- and N-(2-hidroxyethyl)-N-(2-ethylhexyl)-N,N-dimethyl-ammonium bis(trifluoromethanesulfonyl)imide [C8ramCol]+[NTf2]- has been developed by 1H NMR, 13C NMR, ATR-FTIR y ESI-MS. Properties as the viscous flux activation energy, the volume or the molar entropy have been calculated from the experimental data on density and viscosity. Calculations showed that the ramified ionic liquid possess a higher degree of structural order when compared with the linear ionic liquid. Also, their capacity for the recovery of Ag (I) was determined and an extraction level of 98.6% for the linear and 40.5% for the ramified ionic liquid was found. Maximum extraction was found at pH 5.0 with an important selectivity on the extraction of Ag (I) and Cu (II) towards Fe (III). Ag (I) extraction with a phosphonium-based ionic liquid (2,4,4 dimethyl(penthyl) phosphinate de trihexyl(tetradecyl) phosphonium) was also tested. Extraction tests were developed at different concentration values when dissolved in kerosene or kerosene plus decan-1-ol. An extraction level of 80 to 85% was determined with the different mixtures at a maximum recovery pH of 3.0. Spectroscopic characterization (ATR-IR) showed the protonation of the anion in the ionic liquid forming the acid specie. This specie is probably the responsible for the extraction of silver. The formation of a dimeric specie was found in the 31P NMR and the value of the formation constant was calculated

The aim of this work was to improve the homologation methodology for the modification of cyclodextrins (CD) skeleton. After opening of the macrocycle, grafting of an additional saccharidic unit and cycloglycosylation, an expensive functionalized γ-CDs can be obtained from cheap α- or β-CDs. A rigid molecular clamp was grafted on the primary face of the β-CD to limit the redeployment of the oligosaccharide. Ionic liquid (IL) used as liquid support reduced the purification steps to simple liquid/liquid extractions. Two models were studied : IL grafted on the molecular clamp, and IL grafted on the additional saccharidic unit. The later turned to advantage a method of selective α-(1→4) glycosylation developed on a series of model ionic supported carbohydrates. A new CD/IL inclusion complex and the structure of a single crystal of the molecular clamp supported on LI were also described

The first section of this thesis describes the synthesis of a new family of ionic liquid crystalline compounds based on imidazolium cations. The study focuses mainly on the mesomorphic behavior of these materials as a function of the molecule backbone (alkyl tail length). All compounds were fully characterized by polarizing optical microscopy, differential scanning calorimetry and X-ray diffraction studies. We report also the synthesis, lamellar crystal structure and catalytic activity of the palladium (II) complex of the (deprotonated) carbene form of one of these salts. In addition, we measured the charged carrier mobilities in the mesophase. The molecular design of our ionic liquid crystalline materials has then been modified to incorporate cyanometallate to endow the products with electrochemical properties. The second section of this thesis is devoted to the development of a new route for the preparation of metallic nanoparticles by electrocrystallization. This approach allow direct and accurate control of the reduction process, of the size of the nanoparticles and of their density of nucleation on the substrate. Of particular significance is the demonstration herein that the supramolecular structure of the liquid-crystal phase can be used to influence the morphology of metal nanoparticles deposited by electrochemical reduction

Ionic liquids (IL) are molten salts with a melting point below 100 °C. They have numerous advantages compared to usual solvents, including a very low vapor pressure and a good thermal stability. In the context of this thesis, we studied IL for the dissolution and fluorination of uranium oxides. This manuscript starts by a bibliographical study presenting the conversion of uranium in the nuclear fuel cycle, the crystal chemistry of uranium fluorides and ends with a general presentation of ionic liquids. In the second chapter, the solubility of two uranium oxides (UO2 and UO3) is studied in IL commonly used in the literature. The most interesting results are obtained at high temperature (180 °C) with [Hbet][NTf2] and [Bumim][PF6]. With the first one, we observe a good solubility of uranium, whereas [Bumim][PF6] allows the fluorination of UO2 yielding uranium tetrafluoride UF4. In the next chapter, we tried to increase uranium oxides solubility in IL using additional molecules. A significant result is the precipitation of hydrated uranium tetrafluoride (UF4.xH2O) from the addition of aqueous hydrofluoric acid. The following chapter studies the formation of UF4 from the UO2-[Bumim][PF6] mixture in ionothermal conditions (180 °C). Thanks to spectroscopic methods (NMR, XANES/EXAFS), we show that the reaction is initiated by traces of water in the system (14 ppm). Hydrolysis of the IL liberates HF and leads to the precipitation of anhydrous UF4. This documents ends with the use of a non-commercial IL [Emim][F(HF)2,3] which stabilizes hydrofluoric acid in its structure. At 100 °C, this fluorinated IL can fully digest all the uranium oxides that we selected
