Abstract
The invention provides a continuous process for preparing alkylchlorosilanes from the residues of direct synthesis of alkylchlorosilanes which comprise liquid constituents with a boiling point of at least 70° C. at 1013 hPa and may also contain solids, with hydrogen chloride, by passing the residues at a temperature not above 200° C. and hydrogen chloride at a temperature higher than the latter into a reactor so that the resultant reaction temperature is from 400° C. to 800° C.
