Abstract
A process for preparing an acryloyloxysilane, comprising: reacting a metal salt of a carboxylic acid having the formula [CR22═CR1CO−]aMa+ (I), with a haloorganoalkoxysilane having the formula XR3Si(OR4)nR53-n (II) at a temperature of from 50 to 160° C. and in the presence of a catalyst, and in the presence of water, an alcohol comprising 1 to 5 carbon atoms, or a combination of water and an alcohol comprising 1 to 5 carbon atoms, to form a mixture comprising an acryloyloxysilane and a metal halide having the formula Ma+X−a (III), wherein R1 is H, R7COO−Ma+, or C1-C6 hydrocarbyl, each R2 is independently R1 or [COO−]Ma+, 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 hydrocarbyl, each R5 is independently R1 and n is an integer from 1 to 3.
