PRODUCTION OF ORGANOSILANOLS

Japanese Patent JP3543400

B2

PURPOSE: To produce an organosilanol in high purity and yield without contaminating the reaction system with a catalyst by hydrolyzing an organic Si compound containing Si-H bond in the presence of a specific Pd compound catalyst chemically bonded to a specific solid carrier.
CONSTITUTION: This compound is produced by hydrolyzing an organic Si compound containing Si-H bond and expressed by formula I (R1 is a 2-10C univalent hydrocarbon group or a triorganosilyloxy group containing a 1-6C univalent hydrocarbon group; R2 is H or R1; X is O or a 1-6C bivalent hydrocarbon group; (a) is 0-6) in the presence of a catalyst produced by reacting a silicon resin having S and N and expressed by formula II (Y is a ≤11C sulfur-containing univalent organic functional group bonded to Si through Si-C bond; Z is a ≤11C nirogen-containing univalent organic group bonded to Si through Si-C bond; R3 is a 1-4C univalent hydrocarbon group; (b) to (e) are each a positive number satisfying the formulas 0<b<1, 0<c<0.5, c<b, O<b+c<1, 0≤d<0.1, 0<e<1 and 0<b+c+d+e<2) with a Pd compound of formula PdLf (L is ligand which may have mercapto substituent; (f) is a number satisfying the free valence number of Pd) or its complex compound.
