摘要
在催化剂作用下，用氧化钙作脱水剂，采用索氏提取器将对羟基苯甲酸与脂肪醇进行回流脱水直接酯化。酯化反应时间仅需３ｈ，产率达９４％～９６％，同时对影响产率的因素进行考察，确定了最佳反应条件。
Describes a new synthetic method of p hydroxy benzoate from p hydroxy benzoic acid and fatty alcohol. The experiment was carried out by the action of catalytic agent, the dehydration by calcium oxide and using soxhelt extraction apparatus. In this method, only 3h of reaction time are needed, and the yield is up to 94%～96%. The effects of various factors on the reaction yields were examined and the best reaction conditions were found.
