Abstract
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 comminuting fragments of metallic silicon raw material, have a mean particle size of 10 &mgr;m to 10 mm and a surface oxygen quantity of up to 0.3 wt % 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.
