摘　　要：生物柴油是一种绿色可再生能源。该文报道微波辐射下离子液体[Bpy]HSO4催化葵花籽油与甲醇通过酯交换反应制备生物柴油,以正交法对制备工艺条件进行优化,考察醇油物质量比、催化剂用量、微波功率和反应时间对酯交换反应影响。实验结果表明,当醇油物质量比为10∶1、催化剂用量(催化剂与油质量比)为5%、微波功率为400W、反应时间为45min时,生物柴油转化率可达96.2%;与传统加热方式相比,采用微波辐射加热方式,反应时间明显缩短,能耗减少。The biodiesel fuel is a green renewable energy resource. Transesteriflcation of sunflower oil with methanol over ionic liquids [Bpy]HSO4 catalyst under microwave irradiation to prepare biodiesel was studied. Then orthogonal experiment is used to optimize the synthesis process, and the influences of mole ratio of alcohol to oil, catalyst dosage, microwave power and reaction time on the yield were investigated. The perfect technological condition were as follow： n （ methanol ） ： n （ oil ）=10 ： 1, m （ catalyst ） ： m （ oil ）= 0.05, microwave power 400W and reaction time 45 min, conversion of sunflower oil can reach 96.2%. Comparing with conventional heating methods, the transesterification process under microwave irradiation was proved to be faster with lower energy consumption.
