ABSTRACT:
A method is provided for hydrolyzing chlorosilanes, for example, dimethyldichlorosilane, to produce dimethylpolysiloxane hydrolyzate and an aqueous solution of hydrogen chloride along with anhydrous hydrogen chloride. Chlorosilane hydrolysis is effected in the presence of a substantially stoichiometric equivalence of water which results in the direct generation of anhydrous hydrogen chloride and a saturated aqueous hydrogen chloride solution. The saturated aqueous solution of hydrogen chloride can be recycled to the chlorosilane hydrolysis step.
