There is provided an improved process for removing residual silicon and copper powder from the gaseous organohalosilane products of a direct process reactor which utilizes sintered metal filtering elements to filter out the said powder from gaseous organoalosilanes which have been processed in primary and secondary cyclones.

Process for the manufacture of organohalosilanes

A process for recovering and recycling elementary silicon from a direct process organohalosilane reactor system is provided, comprising the steps of analyzing a portion of effluent contact mass, such as the silicon fines from a secondary cyclone with a particle size distribution analyzer, determing the fines fractions containing the relatively greatest amounts of impurities and segregating a relatively impure fine fraction from a purer coarse fraction with the aid of an aerodynamic centrifugal classifier.
