Process for the preparation of alkylchlorosilanes from the residues obtained in the direct process of alkylchlorosilanes

摘要

Continuous production of alkylchlorosilanes from residues from the direct synthesis of alkylchlorosilanes, comprising liquids with a boiling point of at least 70 [deg] C and optionally solids, comprises supplying a reactor with the residues at up to 200 [deg] C and with hydrogen chloride at a temperature such that the reaction temperature is 400-800 [deg] C.
