Abstract

A process for preparing an acryloyloxysilane, the process comprising reacting a metal salt of a carboxylic acid having the formula [CR22═CR1COO−]aMa+ (I), with a haloorganoalkoxysilane having the formula XR3Si(OR4)nR53n (II) in the presence of mineral spirits and a phase transfer catalyst at a temperature of from 50 to 160° C. to form a mixture comprising an acryloyloxysilane and a metal halide having the formula Ma+X−a (III), wherein R1 is H or C1-C6 hydrocarbyl, each R2 is independently R1 or [COO−]aMa+, Ma+ is an alkali metal cation or alkaline earth metal cation, a is 1 or 2, X is halo, R3 is C1-C6 hydrocarbylene, each R4 is independently C1-C10 Q hydrocarbyl, each R5 is independently R1 and n is an integer from 1 to 3.
