| 摘 要： | 以H+改进后的FeCl3/[bmim]Cl离子液体为催化剂,考察了离子液体催化剂中加入质子酸前后对苯与乙烯烷基化反应的影响,结果表明:离子液体中加入质子酸后,其酸度增加,离子液体的催化活性提高。酸性的离子液体具有较高的活性与选择性,并且催化剂可以循环使用,而活性基本没有降低。在优化的反应条件下,乙烯的转化率近100%,乙苯的选择性大于98%。

Alkylation of Benzene with Ethylene Catalyzed by Ionic Liquid Modified with H+ |
| |
| Abstract: | The effects of proton acid added in on alkylation of benzene with ethylene were studied using FeCl3/[bmim]Cl ionic liquid modified with H+ as catalyst The results showed that the activity of ionic liquid correlates well with acidity, and reactive activity of ionic liquid increases with the increasing of the acidity Acidic ionic liquid has higher activity and selectivity, and can be reused, whereas the activity does not reduce At the optimum reaction conditions, approaching 100% conversion of ethylene and more than 98% selectivity of ethylbenzene can be obtained |
