Patent ID: 7700196

Claim:
A process for producing organosilicon compounds containing carbonyl radicals by oxidation of organosilicon compounds containing carbinol radicals with the aid of a mediator selected from the group consisting of the aliphatic, cycloaliphatic, heterocyclic and aromatic NO—, NOH— and group-containing compounds and mixtures thereof, and an oxidizing agent, wherein when the process takes place as a mixture, the organosilicon compound containing carbinol groups is present in a dispersed phase with a particle size of 200 μm or less, wherein the organosilicon compounds having carbinol radicals are those of the formula A′ v R 3-v SiO(SiR 2 O) n SiRA′O) o SiR 3-v A′ v (I″), in which A′ are identical or different radicals of the formula R are identical or different and are a monovalent, linear or cyclic, branched or straight-chain optionally substituted hydrocarbon radical, v is 0, 1, 2 or 3, n is 0 or an integer from 1 to 2000, o is 0 or an integer from 1 to 2000, with the proviso that at least one radical A′ is present, wherein Y 1 is a divalent or polyvalent, linear or cyclic, branched or straight-chain organic radical optionally substituted and/or interrupted by the atoms N, O, P, B, Si or S; Y 2 is a hydrogen atom or a monovalent, linear or cyclic, branched or straight-chain, organic radical optionally substituted and/or interrupted by the atoms N, O, P, B, Si or S; and y, depending on the valency of radical Y 1 is ≧2.
