摘　　要：微波辅助下从歧化松香中提取去氢枞酸,用单因素实验法研究得出最佳提取条件为:乙醇胺与歧化松香的摩尔比1.1∶1,将乙醇胺在5 min内滴完,反应温度75℃,反应时间15 min,异辛烷作萃取剂。去氢枞酸的收率达80.9%,纯度达94.25%。与常规提取法相比,微波辅助法收率高且反应时间短。Dehydroabietic acid was extracted from disproportionated rosin under the microwave irradiation. The optimal extraction conditions were found by single factor experiments to be as follows：the mole ratio of ethanolamine to disproportionated rosin is 1.1 ： 1, feeding time of ethanolamine 5 min, reaction temperature is 75 ℃ ,reaction time is 15 min,with isooctane as extractant. The yield of dehydroabietic acid amounted to 80.9% ,and its purity was 94.25%. In comparison with conventional extraction method, the microwave-assisted method has higher yield and shorter reaction time.
