Process for producing a silicone compound

摘要

This invention provides a process for producing of a silicone compound which includes a synthesis reaction of a silicone compound represented by the following formulas (a) and/or (a'),
by reacting a carboxylic acid represented by the following formula (a2)
to an epoxy silane represented by the following formula (a1)
in presence of a metal salt of the carboxylic acid represented by the general formula (a2), characterized in that the reaction is carried out in presence of 0.05 wt% or more water in said reaction system.
(Here, A denotes siloxanyl group. R 1 denotes a substituent with 1 to 20 carbons having a polymerizable group. R 2 to R 4 respectively and independently denote hydrogen, a substituted or unsubstituted substituent with 1 to 20 carbons, or -X-A. X denotes a substituted or unsubstituted divalent substituent with 1 to 20 carbons.)
