Process for preparing an acryloyloxysilane

A process for purifying an acryloyloxysilane, the process comprising:

• subjecting a mixture comprising an acryloyloxysilane, a haloorganoalkoxysilane, and a non-polar solvent, wherein the non-polar solvent comprises a mixture of 0.5 to 15% (w/w) of a branched-chain alkane having from 5 to 20 carbon atoms and 85 to 99.5% (w/w) of a straight-chain alkane having from 5 to 14 carbon atoms, based on the weight of the branched-chain and straight-chain alkane in the non-polar solvent, and wherein the non-polar solvent comprises less than 5% (w/w), based on the weight of the non-polar solvent, of an aromatic compound, to a temperature and pressure sufficient to vaporize a portion of the non-polar solvent, the haloorganoalkoxysilane, or the non-polar solvent and the haloorganoalkoxysilane from the mixture to produce a purified mixture comprising the acryloyloxysilane.
