ABSTRACT:
A method for hydrolysis and condensation of alkyl/aryl-trichlorosilanes wherein the chlorosilanes are dissolved in liquid hydrogen chloride and the solution is hydrolized at a pressure of 15 to 80 atmospheres and at a temperature of -17.degree. to +47.degree. C. and water is present in an amount of 0.165 to 0.465 moles per chlorine atom attached to a silicon atom. After condensation, the reaction product is freed from hydrochloric acid and unhydrolyzed silanes. Also disclosed are new chlorosilanes prepared by the process of the invention.
