실험 절차

The apparatus of Example B was charged with 148.8 g (1.2 mol) of 1-vinyl-3,4-epoxycyclohexane, 1.3 g of a carboxylic acid promoter, and 0.15 ml 0f 10% chloroplatinic acid catalyst solution. The flask contents were heated to 89° C. and dropwise addition of 122.8 g (1.0 mol) of trimethoxysilane was begun. The reaction temperature was controlled at 90°-95° C. with an ice bath. Reaction was maintained at that temperature for half an hour after completion of addition, which took 18 minutes. Analysis by gas chromatography showed a yield of 90% of 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane. This example demonstrates a standard preparation of 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane using commercial chloroplatinic acid.
