ABSTRACT:
Organohalosilanes are prepared by reacting metallic silicon particles with an organohalide in the presence of a copper catalyst. A contact mass composed of metallic silicon and copper catalyst contains an effective amount of a catalyst powder obtained by mechanical surface treatment of a powder mixture of tin powder and another metal, typically copper powder, on a ball mill, stamp mill, jet mill, mechanofusion device or the like.
