| 摘 要： | 在微波辐射条件下，以对氨基苯磺酸为催化剂，乙二醇和硬脂酸为原料合成了乙二醇单硬脂酸酯。考察了催化剂用量、微波辐射时间、微波功率和醇酸比对反应的影响。得出较佳反应条件为：乙二醇：硬脂酸为1．1：1（mol／mol）、催化剂用量0．3％（质量分数）、微波功率800W、反应时间16min。

| Abstract: | Glycol monostearate was rapidly prepared by esterification of glycol with stearic acid in the presence of catalyst p - amino - benzenesulfonic acid under microwave irradiation. Effects of dosage of the catalyst, irradiation time, microwave power and molar ratio of glycol to stearic acid on the esterification was investigated. The optimum reaction conditions were glycol to stearic acid 1.1 ： 1 （ moL/mol）, dosage of catalyst 0.3 % （ wt）, microwave power 800W, irradiation time 16 min. |
