    摘要: When oganohalosilanes are prepared by charging a reactor with a contact mass containing a metallic silicon powder and a copper catalyst, and introducing an organohalide-containing gas into the reactor to effect the direct reaction, a poly(organo)phosphino compound is added to the contact mass. The invention is successful in producing organohalosilanes at a significantly improved production rate without reducing the selectivity of useful silane.

    摘要: Organohalosilanes are prepared by the Rochow process of reacting metallic silicon particles with an organohalide in the presence of a copper catalyst. The metallic silicon particles, which are prepared by committing fragments of metallic silicon raw material, have a mean particle size of 10 &mgr;m to 10 mm and a surface oxygen quantity of at least 0.05 wt % and/or at least 0.001 g of oxygen/m2 of silicon surface area, which is given as the difference between the oxygen concentrations determined by in-metal oxygen analysis of the metallic silicon particles and the fragments, respectively. On analysis, the metallic silicon particles have been held for at least 3 hours in an air atmosphere at 25° C. and RH 55%
