184 g of 2-ethylcapronic acid allyl ester (prepared from the free acid and allyl alcohol by azeotropic esterification in benzene in the presence of p-toluenesulfonic acid; BP18 : 95° C.; nD20 : 1.4298) was heated to 75° C. in a 3-necked flask provided with stirrer, reflux condenser, internal thermometer and dropping funnel. Then 0.1 ml of an 0.01 molar solution of mesityl oxide-platinum dichloride catalyst complex in acetone was stirred in, and a quantity of 164 g of triethoxysilane was fed in from the dropping funnel within a 6-minute period, during which the temperature rose to 99° C. 10 minutes after the triethoxysilane feed was completed, no more silane hydrogen was analytically detectable. Vacuum distillation of the product yielded 322 g of 3-(2'-ethylcaproyloxy)-propyltriethoxysilane, BP1 : 134°-138° C.
