摘　　要：对γ-氯丙基二甲基甲氧基硅烷的合成进行了研究,在催化剂(氯铂酸作主催化剂,三正丁胺为助催化剂)的作用下γ-氯丙烯与二甲基氯硅烷通过硅氢加成反应生成γ-氯丙基二甲基氯硅烷,蒸馏提纯后,再与甲醇进行醇解反应得最终产品。通过探究反应温度、投料比、催化剂用量等反应条件达到合成工艺的最优化,γ-氯丙基二甲基甲氧基硅烷收率可达69.0%。The synthesis of γ-chloropropyldimethylmethoxysilane was studied. The γ-chloropro-pyldimeth- ylchlorosilane was synthesized by hydrosilylation reaction with γ-dichloropropene and dimethylchlo-rosilane as raw material, chloroplatinic acid as the main catalyst and tri-n-butylamine as the cocatalyst. Distilling the γ-chloropropyldimethylchlorosilane and then methylating, the target product was gained. Through ex- ploring the reaction temperature, the feed ratio and the amount of catalyst, the synthesis conditions were optimized; and the best product yield reached 69.0%.
