A method for hydrolyzing chlorosilanes having at least three chlorine atoms bonded to each silicon atom to form silicone resins. The method comprises adding at least one of hydridotrichlorosilane, tetrachlorosilane, or organotrichlorosilane to a two-phase mixture comprising a non-polar organic solvent, an aqueous phase comprising 0 to about 43 weight percent hydrochloric acid, and a surface active compound selected from the group consisting of alkylsulphonic acid hydrate, alkali metal salt of alkylsulphonic acid, arysulphonic acid hydrate, and alkali metal salt of arylsulphonic acid. |
