ABSTRACT:
An alkylhalosilane is prepared by charging a reactor with a contact mass comprising a metallic silicon powder and a copper catalyst, and feeding an alkyl halide into the reactor whereby the silane is formed by direct synthesis. The use of a metallic silicon powder having a specific particle size distribution ensures effective fluidization whereby the alkylhalosilane of quality is formed at a high selectivity and in high yields.
