摘　　要：考察了超临界甲醇中单酸酯化反应时间、温度、压力及醇酸摩尔比对单酸转化率的影响,研究了反应过程中的化学反应动力学规律。实验结果表明,单酸酯化反应的最佳温度300℃,反应压力15 MPa,反应时间2 h,醇酸摩尔比4∶1。在最佳反应条件下,反应转化率超过95%。The influences on the conversion rate of reaction time, temperature ,pressure ,and molar ratio of methanol to monomer acid the esterification of monomer acid in supercritical methanol were discussed. Reaction kinetics of esterification of monomer acid in supercritical methanol was also investigated. The results showed that more than 95 % conversion rate could be obtained under the optimal reaction parameters of temperature 300 ℃ ,pressure 15 MPa, reaction time 2 h and molar ratio of methanol to monomer acid 4：1.
