Abstract

In the process for the direct synthesis of methylchlorosilanes from chloromethane and silicon in the presence of a copper catalyst and promoter, the reaction mixture comprising chloromethane, methylchlorosilanes, and dust-like components comprising copper, promoter and silicon are removed continuously. The dust-like components are separated from the reaction mixture and cooled with liquid chloromethane.
