| 摘 要： | 介绍了均三甲苯分离技术的新发展，研究开发了一种新工艺，以叔丁醇为烷基化剂，无水三氯化铝为催化剂，通过傅-克烷基化反应将邻甲乙苯转化成沸点较均三甲苯高的重组分，使二者能通过常规精馏的方法得以有效地分离。研究了反应温度、原料配比、催化剂用量等反应条件对烷基化反应的影响，烷基化反应的最佳工艺条件为室温、反应时问2～4h、C9芳烃与烷基化剂(叔丁醇)及催化剂的摩尔配比为1：1：0．4，可使邻甲乙苯100%转化，而均三甲苯损失率小于2％。

| Abstract: | The development of separation of mesitylene was introduced briefly. In order to separate the orth-methylethylbenzene from mesitylene, the Friedel-Crafts reaction of C9 aromatics was studied using tert-butyl alcohol as alkylation reagent and aluminum chloride as catalyst. The influence of reaction such as the proportion of the raw materials, reaction time and the reaction temperature have been discussed. The results show that o-methylethylbenzene could be separated from mesitylene successfully by fractionthis me,thaod. |
