Title:
ORGANOXY SILOXANE MANUFACTURING METHOD AND BORON COMPOUND
Document Type and Number:
WIPO Patent Application WO/2019/004172
Kind Code:
A1
Abstract:
The present invention relates to a novel boron compound and a method for synthesizing a target organoxy siloxane by using a specified boron compound as a catalyst through the reaction of a siloxane containing a SiH group and an organic compound containing an OH group. The method according to the present invention synthesizes organoxy siloxane without using expensive noble metals, and suppresses siloxane side reactions such as disproportionation reactions and balancing/redistribution reactions in order to suppress gelation of the siloxane. The novel boron compound according to the present invention can be used as a catalyst in the method.
