摘要
研究了反应诸因素对水杨酸重排法制备对羟基苯甲酸产率的影响，推荐的反应条件为：反应时间７０ｍｉｎ，反应温度２４０℃，水杨酸与ＫＯＨ的物质的量比为１：１．１。按重量法计对羟基苯甲酸的收率超过３７％。
The influence of various factors on the yield of p-hydroxybenzoic acid prepared from salicylic acid by rearrangement isstudied. The reaction conditions recommended are as follows: reaction time is 70 minutes; reaction temperature 240℃; the molar ratio of salicyiic acid to potassiumhydroxide 1/1.1. The yield in weight of p-hydroxybenzoic acid is more than 37%.
