실험 절차

170.7 g (1 mol) of chloromethyltrimethoxysilane, 11.1 g (0.03 mol) of tri-n-octylphosphine and 0.1 g (0.05 mol % based on silane) of phenothiazine are placed in a reaction vessel at 90° C. and 130.4 g (1.05 mol) of potassium methacrylate are added a little at a time over a period of 1 hour. After stirring at 90° C. for another 1 hour, the reaction is complete. After filtration from the potassium chloride formed, the product is distilled by means of a short-path evaporator, giving 209.3 g (95%) of methacryloxymethyl-trimethoxysilane having a purity of 98.8%.
