| 摘 要： | 以离子液体为催化剂，考察了不同的离子液体、原料中水含量、苯和己烯之比、一定量质子酸对苯和己烯烷基化反应的影响。实验表明，离子液体的催化活性与其酸强度密切相关，只有在酸性条件下，离子液体对烷基化反应才有催化活性。酸性离子液体具有很高的催化活性和很好的烷基苯选择性，并且可以循环使用，活性基本没有降低。在优化的反应条件下，可以得到较高水平的己烯转化率，并且烷基苯的选择性很高。

| Abstract: | The influence of different ionic liquid, water content in feed, molar ratio of benzene to hexene, and added proton acid on alkylation was inspected using ionic liquid as the catalyst. The results showed that the activity of ionic liquid correlated strongly with its acidity, and only acidic ionic liquid had alkylation activity. Acidic ionic liquid had high activity and selectivity, and could be reused without decrease in activity. Under optimum reaction conditions, high conversion rate of hexene and selectivity of alkylbenzene could be obtained. |
