Claim Text:
1. A process for preparing an acryloyloxysilane, the process comprising: reacting a metal salt of a carboxylic acid having the formula [CR 2 2 ═CR 1 COO − ] a− M a+ (I), with a haloorganoalkoxysilane having the formula XR 3 Si(OR 4 ) n R 5 3-n (II) in the presence of mineral spirits, wherein the mineral spirits are petroleum distillates comprising a mixture of isoalkane, alkane, and cycloalkane, 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 M a+ X − a (III), wherein R 1 is H or C 1 -C 6 hydrocarbyl, each R 2 is independently R 1 or [COO − ] a M a+ , M a+ is an alkali metal cation or alkaline earth metal cation, a is 1 or 2, X is halo, R 3 is C 1 -C 6 hydrocarbylene, each R 4 is independently C 1 -C 10 hydrocarbyl, each R 5 is independently R 1 and n is an integer from 1 to 3.
