Reaction Conditions

Reaction Steps

The apparatus of Example B was charged with 136.8 gm (1.2 mol) of allyl glycidyl ether, 2.6 gm of a carboxylic acid promoter and 0.14 ml of 10% chloroplatinic acid solution. The addition funnel was charged with 122.8 gm (1.0 mol) of trimethoxysilane. The contents of the flask were heated to 90° C. and dropwise addition of trimethoxysilane was begun. The exotherm of the reaction was controlled with an ice bath to maintain the temperature at 90°-95° C. The addition was completed. in 25 minutes and temperature was maintained at 90°-95° C. for another hour. Analysis by gas chromatography showed an 86% yield of 3-glycidoxypropyltrimethoxysilane. This example demonstrates a standard preparation of 3-glycidoxypropyltrimethoxysilane using chloroplatinic acid solution as the catalyst.
