Abstract:

Acrylpimaric acid was synthesized under microwave irradiation by using rosin and acrylic acid as raw materials. The effects of reaction time，microwave power，temperature，and mole ratio of acrylic acid to resin acids on the Diels-Alder addition were investigated. The optimum synthesis conditions were obtained as follows：reaction time 60 min，reaction temperature 180 ℃，microwave power 110 W，acrylic acid /resin acids ratio 1.2∶1（mole ratio）. The results showed that microwave could accelerate the reaction rate significantly.

摘要：

以松香和丙烯酸为原料，在微波辐射条件下合成丙烯海松酸，探讨了反应时间、反应温度、微波功率、物料配比等因素对丙烯海松酸含量的影响。确定了微波辐射条件下丙烯海松酸最佳的合成工艺条件：反应时间为1 h，反应温度为180 ℃，丙烯酸和精制松香的摩尔比为1.2∶1，微波辐射功率为110 W。实验结果表明微波辐射能够显著地加速丙烯酸和松香的加成反应。
