Patent ID: 7459514

Claim:
A process for the preparation of organosilicon compounds having silanol groups, of the formula wherein e is from about 80 to about 1000, g is from 0 to 199, h is from 1 to about 200, R each are identical or different monovalent, SiC bonded, optionally substituted C 1-18 hydrocarbon radicals, R 2 is R or —OH, and the sum of g+h is f, comprising reacting an organopolysiloxane (A) having SiH groups, of the formula wherein e is from 80 to 1000, f is from 1 to about 200, R 1 is hydrogen or R, with water (C) in the presence of at least one catalyst (B) selected from the group consisting of metals of subgroup VIII of the Periodic Table of Elements and compounds thereof, further in the presence of at least one cocatalyst (K) comprising an organic acid, a low molecular weight organosilicon hydride, or a mixture thereof.
