| 摘 要： | 以双环戊二烯、丙烯酸、水为原料，采用两步法合成丙烯酸双环戊二烯基酯。首先以硫酸为催化剂，双环戊二烯经过水合制得羟基双环戊烯，再以羟基双环戊烯和丙烯酸为原料经过酯化反应得到丙烯酸双环戊二烯基酯与传统的以双环戊二烯与丙烯酸为原料直接加成生成丙烯酸双环戊二烯基酯的工艺相比，减轻了后续的处理工作，提高了产品收率。酯化反应的优化条件为：n（丙烯酸）：n（羟基双环戊烯）为1．1、催化剂二丁基氧化锡用量2．5％（质量分数，以羟基双环戊烯质量为基准，下同）、阻聚剂对羟基苯甲醚用量0．1％、带水剂为50％（其中环己烷用量为20．0％、甲苯用量为30％）、反应温度为99℃，反应时间是4h。在此条件下合成的丙烯酸双环戊烯基酯的收率达92％以上，纯度达94．4％。

| Abstract: | Two-step method was applied as well as dicyclopentadiene,acrylic acid and water were used as raw material in this experiment.Firstly,hydroxy-dicyclopentadiene was obtained through dicyclopentadiene after hydration with using sulfuric acid as the catalyst.Then the dicyclopentadienyl acrylate was prepared by esterification reaction with using hydroxy-dicyclopentadiene and acrylic acid.Compared with the traditional technology,which used direct addition of dicyclopentadiene and acrylic acid,it reduced the post-... |
