The invention relates to a process for preparing alkylchlorosilanes from the liquid constituents of the residues from the direct synthesis of alkylchlorosilanes which have a boiling point of above 70°C at 1013 hPa and comprise disilanes, in which the residues are heated with hydrogen chloride and silicon at temperatures of at least 300°C, with at least 10% by weight of trichlorosilane and/or tetrachlorosilane, based on the weight of the alkylchlorosilanes formed, being formed at the same time.
