采用Grignard反应一步法合成了二环己基二甲氧基硅烷.14 g镁屑、11g氯代环己烷和30 g THF投入反应瓶,在回流状况下滴加由36.4 g四甲氧基硅烷、44 g氯代环己烷和120 g石油醚90～120组成的混合溶液；回流4h后冷却,过滤；母液精馏得产物55 g,收率86.9％(以四甲氧基硅烷计),质量分数≥99.0％.%Dicyclohexyldimethoxysilane was synthesized by one step Grignard reaction method.Firstly,14 g magnesium, 11 g chlorocyclohexane and 30 g THF were added into the flask. Then 36.4 g tetramethoxysilane, 44 g chlorocyclohexane and 120 g petroleum ether 90~120 were added to the system in the case of reflux. After 4 h, 55 g dicyclohexyldimethoxysilane was obtained by separation and rectification. The yield was 86.9%, the purity was 99%.
