Abstract
There is provided a method and a catalyst for the direct production of organohalosilanes from elemental silicon and an alkylhalide. The catalytic material is characterized by the presence therein of zinc, the source of zinc in said catalyst being selected from the group consisting of zinc carbonate, zinc formate, zinc acetate, zinc vinyl acetate, zinc propionate, zinc butyrate, zinc beta-chlorobutyrate and zinc gamma-chlorobutyrate. These sources of zinc overcome problems encountered with zinc metal and zinc halides, commonly used as sources of zinc.
