摘要
以对羟基苯甲酸和正丙醇为原料,HClO4-Si O2为催化剂,经过回流脱水酯化法直接合成对羟基苯甲酸丙酯。催化剂循环使用6次,酯化率可高达90.1%。该反应产率高、反应时间短、操作简单等优点。
The Synthesis of propyl p-hydroxybenzoate from p-hydmxybenzoic acid and propanol using HClO4-SiO2 as the catalyst under the circumfluent dehydration conditions.When the catalyst was used for 6 times without any treatment,the yield of esterification product could get high yield 90.1%.This reaction has advantages of high yields,short reaction time,easy of workup.
