The invention relates to copper-based catalysts, processes for their production and their use and to a process for the production of alkyl halosilanes in the presence of said catalysts.

Copper-based catalysts, processes for their production and their use and

The process for producing alkylhalogenosilanes, which comprises reacting a physical mixture of silicon, a selenium or tellurium promoter and a copper catalyst with an alkyl halide.

Process for producing alkylhalogenosilanes

Metallurgical silicon containing phosphorus for the preparation of

Fine particle silicon containing surface-bound halogen, a process for

Metallic silicon for the Rochow-Synthesis is reduced to particles measuring at least 5 mm in their smallest dimension and 15 mm in their largest dimension, cooling the silicon from a temperature of at least 700.degree. C. to at most 120.degree. C. within a maximum of 2 seconds, and then ground and reacted.

Process for the preparation of organochlorosilanes

A process for the preparation of alkyl halogenosilanes comprising reacting silicon with alkyl halide in the presence of a copper catalyst and promoter substances and phosphorous and phosphorous compounds in combination with indium or indium compounds or aluminum or aluminum compounds or a mixture of aluminum or aluminum compounds and indium or indium compounds.
