摘　　要：以氢化松香甘油酯为原料,研究了低温常压均相酯交换法制备氢化松香甲酯的方法。通过气相质谱联用仪对反应产物的成分进行分析,并探讨了温度、催化剂用量、反应时间和甲醇用量对氢化松香甘油酯转化率的影响。通过正交实验获得了氢化松香甘油酯的最适宜的酯交换工艺参数为:反应温度为60℃,催化剂的用量为原料质量的9%,反应时间为11 h,氢化松香甘油酯与甲醇的摩尔比为1∶8。在此条件下,氢化松香甲酯的转化率为93.21%。The preparing method of methyl ester of hydrogenated rosin is studied by homogeneous transesterification at low temperature and atmospheric pressure using the glycerol ester of hydrogenated rosin as the raw material. The components of product are analyzed by GC-MS. The effects of temperature, catalyst dosage, reaction time and methanol dosage on the conversion rate are studied. The orthogonal intersection tests are performed. The optimal process parameters are ：60 ℃ of reaction temperature, 8 wt% of catalyst dosage, 10 hours of reaction time and 1 ： 8 molar ratio of glycerol ester of hydrogenated rosin to methanol. Under the optimized experiment conditions, the conversion yield is 94. 21%.
