This invention relates to an improved process for preparing, purifying and/or storing methacryloxy or acryloxy containing organosilicon compounds without the undesirable polymerization normally associated with the methacrylate bonds. In an alternative embodiment, the process is even further improved with the addition of certain stabilizers, and in particular diketone or ketoester stabilizers.

A process for removing acidic impurities from alkoxysilanes obtained from halogenosilanes and alcohols which inevitable contain small amounts of acidic impurities is described. In the process, at least one member selected from alkali metal salts of alcohols and amines having a great steric hindrance as having a bulky substituent is added to the alkoxysilane for a time sufficient to neutralize the acidic impurities and the mixture is purified by distillation to obtain a substantially acidic impurity-free alkoxysilane.
