실험 절차

In a 10-liter flask provided with stirrer, reflux condenser, internal thermometer and 2 dropping funnels, one filled with 2.85 kg of allyl glycidyl ether and the other with 3.05 kg of trimethoxysilane, 500 ml of allyl glycidyl ether or gamm-glycidyloxypropyltrimethoxysilane was heated to 130° C. Then 1 ml of an 0.01 molar solution of the mesityl oxide-platinum dichloride complex in acetone was added and the reaction was allowed to take place with rapid stirring and the simultaneous feeding in of the two reactants, within about 20 minutes. The internal temperature was kept between 130° C. and 140° C. by slight external cooling and by regulating the feed. This was followed by vacuum distillation producing 5.4 kg of γ-glycidyloxypropyltrimethoxysilane boiling at BP0.05 81° C. (nD20 : 1.4290, d420 : 1.073).
