摘要： When oganohalosilanes are prepared by charging a reactor with a contact mass containing a metallic silicon powder, a copper catalyst and a co-catalyst, and introducing an organohalide-containing gas into the reactor to effect the direct reaction, the catalyst and/or co-catalyst used in the contact mass is obtained by mixing particles of the catalyst and/or co-catalyst with finely divided silica, and applying shear forces to the mixture for mutually rubbing the particles, thereby producing the catalyst and/or co-catalyst having finely divided silica fused to surfaces thereof. The invention is successful in producing organohalosilanes at a significantly improved formation rate without reducing the proportion of diorganodihalosilane.

摘要： In a Rochow process, organohalosilanes are prepared by reacting metallic silicon particles with an organohalide in the presence of a copper catalyst and a co-catalyst. The invention uses as the co-catalyst a powder of co-catalyst active element-copper alloy containing substantial strain energy because this co-catalyst can reduce the activation time taken until a steady state is reached, which has been an outstanding problem in Rochow reaction, maintain the steady state over time and increase the selectivity of desired diorganodihalosilane for eventually increasing the yield based on the starting silicon.
