Abstract
A process for hydrolysing chlorosilanes comprises adding a composition comprising 15 to 100 mole per cent of at least one organotrichlorosilane (RSiCl3), 0 to 50 mole per cent of at least one organochlorosilane of formula R2SiCl2, R3SiCl, RHSiCl2 or R2HSiCl, and 0 to 85 mole per cent of at least one inorganic chlorosilane of formula HSiCl3 or S SinCl2n\sB2, where n is an integer and each R is an alkyl, aryl or alkenyl radical, to an excess of water containing 1 to 50% by weight of the chlorosilane composition of silica having an average particle size within the range of 3 to 100 millimicrons. The powdery products may be used as fillers for silicon rubber stocks and as hydrophobing agents for cements. Examples are given of the process using fume silica and various chlorosilane compositions. Specification 650,830 is referred to.
