1. A process for the manufacture of hydrogenated silane by redistribution, characterized in that - a silane represented by the formula : Hm SiX4-m in which X denotes a halogen or an alkoxy group and m denotes an integer equal to 0, 1, 2 or 3, is reacted with - an alkyl or aryl hydrogenosilane represented by the formula : Rn Hp SiX'4-(n+p) in which X' denotes a halogen or an alkoxy group, R denotes an alkyl or aryl group and n and p, which may be identical or different, denote integers equal equal to 1, 2 or 3 with n + p =< 4 ; - in the presence of a catalyst chosen from the group formed by : quaternary ammonium salts corresponding to the formula R'4 NY, quaternary phosphonium salts corresponding to the formula R'4 PY, in which formulae R', which may be identical or different, denote a monovalent hydrocarbon or halohydrocarbon radical and Y a halogen ; tertiary amines of the general formula NR'R"R"' in which R', R", R"' are monovalent hydrocarbon radicals which may be identical or different ; ion exchange resins containing tertiary amine groups or quaternary ammonium groups ; and the hydrogenated silane or silanes formed is, or are, recovered. |
