Abstract

Alkylchlorosilanes are prepared continuously from the residue of direct synthesis of alkylchlorosilanes containing liquid constituents with a boiling point of at least 70.degree. C. at 1013 hPa and solid constituents, by heating the residue with hydrogen chloride at temperatures of from 300.degree. C. to 800.degree. C. in a tubular reactor with internals which can be rotated.
