摘　　要：制备了具有酸性功能的离子液体[Hnmp]HSO4,并用其催化菜籽油酯交换制备生物柴油.该离子液体表现出良好的催化活性及稳定性.在醇油比为8∶1、反应温度(100±2)℃、反应时间5h和[Hnmp]HSO4的用量为菜籽油质量的8%时,生物柴油收率可达85.4%.并且该离子液体有较好的稳定性,循环使用4次后仍有较高的催化性能.The ionic liquid [Hnmp]HSO4 was prepared, and used to synthesize biodiesel from rapeseed oil by transesterification. Ionic liquid [Hnmp]HSO4 exhibited good catalytic activity and stability. The optimum reaction conditions were obtained as follows, dosage of ionic liquid 8% （based on the mass of rapeseed oil）,molar ratio of methanol to rapeseed oil 8：1,reaction temperature （100±2）℃ , reaction time 5 h. The yield of biodiesel reached 85.4% under the optimum conditions. The ionic liquid was stable, and its activity did not decrease after using for four times.
