摘要: 在微波辐射下,先将氢化松香与聚乙二醇进行酯化反应,合成中间体氢化松香聚乙二醇酯,再将中间体与柠檬酸进行酯化反应,合成目标产物氢化松香聚乙二醇柠檬酸酯。探讨了中间体和目标产物的合成条件, 得出中间体合成的最佳条件为:反应时间 90 min,反应温度 240℃,氢化松香与聚乙二醇的物质的量之比为1:1.6;目标产物合成的最佳条件为:反应时间 60 min,反应温度 150℃,微波功率 500 W。微波辅助法比常现加热法节省时间。利用红外光谱对中间体和目标产物进行了结构表征,并测定了它们的主要表面性能。结果表明,中间体和目标产物均为性能优良的新型非离子表面活性剂。

Abstract: Under microwave irradiation, hydrogenated rosin-polyethylene glycol ester was synthesized as an intermediate by esterification of hydrogenated rosin and polyethylene glycol, and then the target product hydrogenated rosin-polyethylene glycol-citric acid ester was prepared by further esterification of the intermediate and citric acid. The optimal synthetic conditions of the intermediate and target product were investigated. The optimal synthetic conditions of the intermediate were as follows:reaction time 90min,reaction temperature 240℃,the molar ratio of hydrogenated rosin to polyethylene glycol 1:1.6. The optimal synthetic conditions of target product were as follows:reaction time 60min,reaction temperature 150℃,microwave power 500 W. The reaction time of microwave irradiation is shorter than that of common heat method. The intermediate and target product were analyzed and characterized by IR spectroscopy. In addition, their major surface properties were determined. The results showed that both the intermediate and the target product were novel and excellent nonionic surfactants.

Key words: hydrogenated rosin-polyethylene glycol-citric acid ester, microwave irradiation, surfactant, synthesis
