摘要:A process for the direct synthesis of organochlorosilanes using CuCl prepared from the copper-containing residues from the direct synthesis of organochlorosilanes, where, in the preparation of the CuCl, in a first step, copper from an aqueous suspension of the copper-containing residues is oxidized to CuCl2 using mineral acid and oxidant, where mineral acid or oxidant or mineral acid and oxidant contain chlorine, giving an aqueous CuCl2 solution, and in a second step, the aqueous CuCl2 solution is reduced to CuCl using elemental iron.
