摘　　要：为了考察微波辐射对自制固体酸催化剂催化活性的影响,作者以绿豆为原料,采用碳化-磺化法制备了一种新型碳基固体酸催化剂,于实验室自制微波反应器中催化油酸和甲醇的酯化反应。对油酸甲酯化反应过程中的微波功率、反应温度、反应时间、催化剂用量、醇油摩尔比等条件进行了单因素分析,并对醇油摩尔比、反应时间、催化剂用量对油酸甲酯化的转化率的影响进行了正交优化,得到最佳工艺为:微波功率400 W、反应温度65℃、醇油摩尔比11∶1、反应时间30 min、催化剂用量为5%,在此工艺条件下油酸甲酯化的转化率为93.97%。To study the effect of microwave irradiation on the catalytic activity of carbon-based solid acid catalyst made from mung-bean,the catalyst was successfully prepared by carbonization after with sulfonation process and used in methyl esterification of oleic acid by the self-made microwave reactor in laboratory. To select the appropriate reaction conditions,the single factor,including microwave power,reaction time,temperature,catalyst amount and the molar ratio of methanol and oleic acid was studied and based on this result,the orthogonal test was designed to optimize the process parameter. At last,the optimized process condition was microwave power 400 w,temperature 65 ℃,the molar ratio of methanol and oleic acid 11∶1,reaction time 30 min and catalyst amount 5% with 93.97% methyl ester yield.
