Process for preparing organohalosilanes |
摘要 |
Organohalosilanes are prepared by reacting metallic silicon with a halogenated hydrocarbon in the presence of a copper or copper compound catalyst and an activated aluminum, aluminum alloy or aluminum carbide promotor. The reaction is carried out at a temperature of 250-400° C. in a stirred tank reactor or a fluidized bed reactor. The inventive process shortens the time required for activation in the Rochow reaction and increases the selectivity for desirable diorganodihalosilanes. The steady state is thus prolonged and conversion of the silicon enhanced, resulting in an improved reaction performance.
