| 摘要 |
Catalyst comprising copper and a promoter is used to produce alkyl halosilanes by reacting an alkyl halide with a solid contact material comprising silicon and the catalyst, where the promoter comprises (by weight of silicon): 10-500 ppm tin, optionally 0.01-3% zinc, 0.01-2% alkali metal (cesium, potassium and/or rubidium) and optionally 50-3000 ppm phosphorus. An Independent claim is also included for production of alkyl halosilanes by 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, 0.01-3% zinc, 0.01-2% alkali metal (cesium, potassium and/or rubidium) and 50-3000 ppm phosphorus. |
