Abstract
When oganohalosilanes are prepared by charging a reactor with a contact mass containing metallic silicon and a copper catalyst and introducing an organohalide-containing gas into the reactor to effect the direct reaction, 50-10,000 ppm of bronze phosphide is added to the contact mass. The invention is successful in efficiently producing organohalosilanes in a high STY and low T/D.
