| 中文摘要: |
| 以L-脯氨酸和氢溴酸为原料,合成了L-脯氨酸离子液体,并将其固载于CuI之上,制成了双功能脯氨酸离子液,对Knoevenagel反应中催化剂的用量,反应时间,反应温度,反应溶剂等作了初步考察和优化,并得出比较适合的反应条件。这种双功能离子液具有可回收的优点,且催化剂比较稳定,可回收重复使用。 |
| 英文摘要: |
| L-proline ionic liquid was synthesized with L-proline and hydrobromic acid,and it was immobiled CuI to form bifunctional proline ionic liquid.It was applied in Knoevenagel reaction,Amount of catalyst,,reaction time,reaction temperature,and reaction solvent,was investigated and the parameters were optimizated.We concluded that the bifunctional proline ionic liquid was suitable for Knoevenagel condensation,and the catalyst can be recycled. |
