Title:
オメガ-ハロアルキルジアルキルシランの製造方法
Document Type and Number:
Japanese Patent JP4659029
Kind Code:
B2
Abstract:
The present invention relates to a method for preparing an omega-haloalkyl dialkylhalosilane by means of a hydrosilylation reaction in the presence of a catalytically effective amount of a hydrosilylation catalyst containing a platinum group metal. The catalytic metal is recovered by (i) subjecting the distillation residue to controlled hydrolysis to release the gaseous H-Hal haloacid, and providing an aqueous medium containing the catalytic metal with a low hydrolysable halide content Si-Hal=2%, expressed by weight of Hal, then (2i) recovering the platinum group catalytic metal from said aqueous medium by means of one of the conventional techniques specific to catalyst manufacturers that do not use a solid adsorbent and operate in ordinary facilities that do not have to be acid-resistant.
