摘要 以三甲氧基硅烷与γ-氯丙烯为原料,以自制多羰基配位钌的氯化物为催化剂合成了γ-氯丙基三甲氧基硅烷。考察了溶剂环境、催化剂用量、反应温度、加料方式、物料配比及反应时间等对反应产物的影响。较佳的反应条件为:在无溶剂环境下,温度为75~95℃,钌催化剂用量为40×10-6,三甲氧基硅烷与γ-氯丙烯的量之比为1. 05~1. 15∶1,采用γ-氯丙烯滴入三甲氧基硅烷的加料方式,保温2 h。此条件下,γ-氯丙基三甲氧基硅烷的收率达96%。 The synthesis of γ -chloropropyltrimethoxy silane from trimethoxysilane and γ -chloropropene was studied. The effects of solvent environment, amount of catalyst, reaction temperature, feeding sequence, material ratio and reaction time on the reaction products were discussed. The results show that the temperature ranges from 75℃ to 95℃ in the solvent-free environment. When the amount of ruthenium catalyst was 40μg/g, the molar ratio of trimethoxysilane to γ -chloropropene was 1.05, 1.15∶ 1, the target yield of γ -chloropropyltrimethoxy silane was 96%, which was synthesized by dropping γ -chloropropene into trimethoxysilane.
