Abstract: The invention concerns the upgrading of a by-product of direct synthesis, namely MeSiCl3, by vapor phase catalytic hydrogenation of said by-product to obtain MeHSiCl2 with greater added value. The invention concerns a method for preparing MeHSiCl2 by catalytic hydrogenation of MeSiCl3 in the presence of a metal catalyst with high selectivity levels in MeHSiCl2 economically and without having recourse to drastic and industrially unsuitable conditions. The invention uses a catalyst comprising a bimetal ruthenium/tin catalytic agent. Said catalytic agent is obtained by reacting ruthenium chloride and tin chloride in an acid medium. In practice, the catalyst is formed by a silica powder support impregnated by the ruthenium/tin catalytic agent.

Abstract: Elle concerne plus particulièrement un procédé de préparation de cyclohexanone présentant une teneur en impuretés permettant une utilisation de la cyclohexanone comme matière première pour la fabrication d'ε-caprolactame.Le procédé de l'invention comprend notamment un traitement du mélange cyclohexanol/cyclohexanone issu de l'oxydation par l'oxygène du cyclohexane dans une étape de déshydrogénation pour transformer le cyclohexanol en cyclohexanone et les impuretés présentes telles que le cyclopentènal. Le procédé de l'invention permet d'obtenir une cyclohexanone présentant un degré de pureté élevé, compatible pour son utilisation comme matière première dans la synthèse de l'ε-caprolactame.

Abstract: The invention concerns a method for preparing hydrogenated alkylmonosilanes, by catalytic hydrogenolysis, under hydrogen pressure, of halogenoorganopolysilanes, improving known methods, in particular by facilitating implementation, and in terms of cost-effectiveness and performance which are shown by the efficiency of the resulting hydrogenated monosilanes. In said method the starting polysilanes are of the type: (CH3)Cl2Si-SiCl(CH3)2; (CH3)Cl2Si-SiCl2(CH3); (CH3)Cl2Si-Si(CH3)3; (CH3)2ClSi-SiCl(CH3)2; (CH3)Cl2Si-SiCl(Ch3)-SiCl2(CH3); (CH3)Cl2Si-Si(CH3)(SiCH3Cl2)-SiCl2CH3. The hydrogenated monosilanes CH3H2ClSi; (CH3)2HClSi; CH3HCl2Si are obtained by contacting said polysilanes with gaseous hydrogen under pressure, in the presence of a catalytic system AB comprising a hydrogenation catalyst precursor A and an auxiliary B for dissolving precursor A in the reaction medium. Said catalytic system is further characterized in that it is reductant-free.
