Texto completoSilver iodide is a key-compound in nuclear chemistry either in accidental conditions or during the reprocessing of spent nuclear fuel. In french reprocessing plants, iodine is trapped in the dissolver off-gas treatment unit by scrubbing with a caustic soda solution and by chemisorption on mineral porous traps impregnated with silver nitrate, leading to the production of silver iodide and silver iodate. Enhanced separation policy would make necessary to recover iodine from the filters by silver iodide dissolution during a reducing treatment. For this purpose, ascorbic acid and hydroxylamine were used

Texto completoThis work aims at modelling the processes involved in gamma-radiolysis of methyl iodide diluted in air in presence of steam. It is to determine quantitative and qualitative information to quantify the importance of the organic iodides destruction in case of a nuclear reactor accident. The main data for radiochemistry and iodine compounds (IxOy and INOx) formation were reviewed and analysed. Literature data about air products radiolysis reactivity towards I2 and CH3I were used to develop a mechanistic model for methyl iodide destruction in the gas phase under gamma irradiation. An ab initio study was realised for a better understanding of atomic nitrogen (4S and 2D) reactivity towards CH3I. The model was tested on the available experimental data and constitute a way to investigate the main processus involved in methyl iodide destruction. For the low CH3I concentrations, about 10-7 - 10-8 mol. Dm-3, N and e- are mainly responsible for the destruction. I2O4 (highest iodine oxyde in the model) and IONO2 are the main resulting iodinated compounds

Texto completoDuring a severe accident occurring to a pressurized nuclear water reactor, radiological consequences are related to the transport and deposition of radionuclides released into the environment. Following the Fukushima Daiichi accident, significant differences between measurements and simulations were observed for iodine deposition. It could notably be explained by the absence of any iodine chemistry in the IRSN dispersion codes. To address this, a mechanism of atmospheric iodine chemistry involving 257 reactions was developed from a critical review of the literature. In parallel, missing thermokinetic data were determined by molecular-scale simulations for the X + H2O2 (X = Br, I) and OH + CH2IOH reactions. 0D and 3D simulations were performed using ASTEC and Polair3D after an injection of either I2 or CH3I. The results showed a partial and rapid transformation of these iodinated gaseous compounds. The influence of several parameters (air quality, quantity and nature of iodine released) on iodine speciation was evaluated. For all simulations, iodine is quickly found in the form of iodine oxides and nitroxides or gaseous iodocarbon compounds. The latter may be the cause of iodinated aerosols formation and deposition

Texto completoCatalysed asymmetric reactions are an elegant approach towards the synthesis of complex molecules for the controlled introduction of stereocenters. Within this field, oxidations are noteworthy since they allow to create in one step both the stereogenic elements and the moieties whose reactivities are the cornerstone of the methodologies of synthesis. The selectivity of a catalyst is most often controlled by its own structure. Our group has investigated catalysed asymmetric aerobic oxidations by C-H activation through the use of chiral analogues of N-hydroxyphtalimide (NHPI). We have developed a new structure of catalyst based upon a BINOL-fused maleimide core to circumvent the inherent limitations of previous catalysts generations. The first series showed no enantioselectivity and led us to synthesize a second series whose features are expected to improve the overall efficiency of those catalysts for asymmetric aerobic oxidations. The development of an analogue bearing two iodine moieties prompted us to study this structure as a core for chiral hypervalent organo-iodine(lll) catalysts. We have investigated three series of such catalysts for the asymmetric α-oxytosylation of prochiral ketones and showed that our structure is comparable with the ones found in the literature
