| 摘 要： | 制备Brnsted-Lewis双酸性离子液体催化剂［Emim］HSO4-AlCl3，并用于催化1-丁烯齐聚反应，考察催化剂用量、反应压力、反应温度和反应时间对1-丁烯齐聚产物选择性的影响。结果表明，强酸性离子液体催化1-丁烯齐聚反应得到的产物主要为四聚体。在n(AlCl3)∶n(［Emim］HSO4)=1∶1、催化剂用量2.5 g、反应温度30 ℃、反应压力0.08 MPa和反应时间1.0 h条件下进行齐聚反应，产物选择性和反应体系的稳定性较理想。

| Abstract: | Brnsted-Lewis acidic ionic liquid Emim]HSO4-AlCl3 was prepared and used as the catalyst for 1-butene oligomerization.Effects of catalyst dosage,reaction pressure,reaction temperature and reaction time on the selectivity to oligomerization products were investigated.The results showed that 1-butene oligomerization products were mainly tetramers in the presence of acidic ionic liquid.Favorable selectivity and stability were obtained under following condition: n(AlCl3)∶ nEmim]HSO4=1∶ 1,catalyst dosage 2.5 g,reaction temperature 30 ℃,reaction pressure 0.08 MPa,reaction time 1 h. |
