提纯连三甲苯的新方法

New methods of Purifying 1,2,3-trimethylbenzene

目的是对混合C9芳烃中的连三甲苯进行烷基化-减压精馏-脱烷基-减压精馏从而使连三甲苯得以提纯的新方法。即通过分步实验对新方法的可行性进行了论证,并得出可行的依据及较佳的工艺参数。

The main purpose of this paper is to mix C9 aromatic trimethylbenzene for alkylation-reduced pressure distillation-take off alkyl-reduced pressure distillation and alkyl trimethylbenzene purifying new methods. That means to prove the feasibility, and its feasible basis and better technology parameters through this new method.
