Abstract: A method for converting organosilanes by reacting at least one silane (1) of the general formula RaSiCl4-a??(I) with at least one further silane (2) of the general formula RbSiCl4-b??(II) wherein silane (2) is identical or different from silane (1), optionally with additional use of silanes (3) which contain Si-bonded hydrogen and have the formula RdHeSiCl4-d-e??(III) in the presence of aluminum salts, preferably aluminum halides, as catalysts and in the presence of cocatalysts, to obtain at least one silane (4) which differs from silanes (1) and (2) and has the general formula RcSiCl4-c??(IV).

Abstract: Organopolysiloxanes having an OH content of 3.0-10.0% by weight are produced in a continuous process in which silanes of the formula I R1mSiR2nXo??(I), in which R1 is a C1-C18-hydrocarbon radical and R2 is a C1-C6-alkoxy radical and X is a chlorine or bromine radical m is 1, 2 or 3, n is 0, 1, 2 or 3 and o is 0, 1, 2 or 3, with the proviso that 4?m=n+o, and that in at least 30 mol % of the silanes of the general formula I, n?0 und o?0, water, and water-insoluble non-polar solvent are metered in continuously into a reactor to form a reaction mixture and the reaction mixture is continuously discharged from the reactor.
