Production of alkyl halosilanes comprises reacting an alkyl halide with a contact material comprising silicon and a catalyst comprising copper and a tin/alkali metal/phosphorus promoter

摘要

Production of alkyl halosilanes comprises reacting an alkyl halide with a solid contact material comprising silicon and a catalyst comprising copper and a promoter comprising (by weight of silicon): 10-500 ppm tin, 0.01-2% alkali metal (cesium, potassium and/or rubidium) and 50-3000 ppm phosphorus. An Independent claim is also included for a catalyst as above.
