摘要
以乙烯基三氯硅烷和三氟乙醇为原料,二氯甲烷为溶剂合成了乙烯基三(2,2,2-三氟)乙氧基硅烷。考察了原料配比、溶剂用量、Ar2流量、三氟乙醇滴加速度、温度、反应时间等因素对产物收率的影响,确定了最佳合成条件。并运用FT-IR、1 H-NMR、13 CNMR对产物结构进行了表征。
Vinyltrifluoropropylethoxysilane was synthesized by alcoholysis reaction in dichloromethane with vinyl-trichlorosilane and 2,2,2-trifluoroethanol. The influence of reaction conditions such as staple ratio, solvent dosage, argon gas flow, dripping speed, temperature and reaction time were observed. The optimum conditions for synthesizing vinyltriflu-oropropylethoxysilane were established. The structure was characterized by FT-IR,^1H-NMR and ^13 CNMR.
