Synthesis of β-(3,4-epoxycyclohexyl)ethyltrimethoxysilane

β-(3,4-epoxycyclohexyl)ethyltrimethoxysilane(A-186) was synthesized from 1,2-epoxy-4-vinycyclohexane and trimethoxysilane catalyzed by chloroplatinic acid-phenothiazine-triphenylphosphine system.The main effects of the reaction on the yield were discussed and the optimum experimental conditions were found.Results showed that the yield of A-186 reached 92.3% at 95~105℃,when the mass fraction of platinum was 3×10-6,the molar ratio of trimethoxysilane and 1,2-epoxy-4-vinycyclohexane was 1.05,the reaction time was 1.5 hours,and the yield of β-(3,4-epoxycyclohexyl)ethyltrimethoxysilane was 92.3%.
