| 中文摘要: |
| 合成了酸性离子液体\[HNMP\]CH3SO3，并用于催化菜籽油酯交换制备生物柴油。采用响应面法对离子液体 \[HNMP\]CH3SO3催化菜籽油酯交换制备生物柴油的工艺参数进行优化，获得的最佳反应条件为：反应温度100 ℃,醇油摩尔比9∶ 1，催化剂用量10%，反应时间12 h。在最佳条件下，生物柴油转化率为 84.8%。该离子液体有较好的稳定性，循环使用4次后生物柴油转化率仍可达到79.6%。 |
| 英文摘要: |
| The acidic ionic liquid \[HNMP\]CH3SO3 was synthesized and used to catalyze the transesterification of rapeseed oil to prepare biodiesel. The response surface methodology was used to optimize the process parameters of ionic liquid \[HNMP\]CH3SO3 catalyzed transesterification of rapeseed oil to preparing biodiesel. The results showed that the optimal reaction conditions were obtained as follows: reaction temperature 100 ℃, molar ratio of methanol to rapeseed oil 9∶ 1, catalyst dosage 10% and reaction time 12 h. Under these conditions, the conversion rate of biodiesel was 84.8%. The ionic liquid had good stability, and the conversion rate of biodiesel could still reach 79.6% when it was recycled for four times. |
