摘　　要：松香在一定的条件下与丙烯酸发生Diels-Alder双烯加成反应,本文对影响反应的各因素:反应温度、催化剂的质量用量、反应时间、原料配比等进行了系统研究;通过正交试验,确定了松香与丙烯酸的最佳反应工艺条件:反应温度230℃,催化剂的质量用量为松香质量的3.0%,反应时间3.5 h,松香与丙烯酸的质量用量配比4.5∶1。经过3次稳定性试验证明,所得反应条件为最佳合成工艺,加成物含量均在86%左右。In certain condition, it occurs the Diels -Alder reaction that between rosin and acrylic acid. Factors as temperature, dosage of catalyst, time of reaction, proportion of material which influenced the Diels- Alder reaction were systematically studied and in further designed orthogonal experiment, it ascertained the prime technical condition, namely reaction temperature 230℃, dosage of catalyst 3.0% , time of reaction 3.5h, proportion of material 4.5： 1. It was proved that the result of orthogonal experiment is the prime technical condition by three times stable experiments. The even content is 86%.
