摘要
本文研究了甲壳质负载四氯化锡做催化剂合成对羟基苯甲酸丁酯。考察了酸醇比、催化剂用量、反应温度、反应时间对反应的影响。实验结果表明:反应物酸醇比1︰3.5,催化剂用量1.2g,反应温度118℃,反应时间为2.5h,酯化率最高达81%。并对催化剂重复使用效果进行了研究。
This paper studies that the chitin loading tin tetrachloride as the catalyst synthesizes hydroxy butyl benzoate. Also it inspects the a-cid mellow ratio,the catalyst amount used,the reaction temperature,and the reaction time to response influence. The experimental result indicates that,the acid mellow ratio is 1︰3.5,catalyst amount used is 1.2 g,the reaction temperature is 118℃,the re-action time is 2.5 h,and the esterification rate reaches up to 81%. And it makes a research on the effect of catalyst repetition use.
