摘　　要：本文以C10重芳烃为原料,先采用精馏的方法获得间二乙苯、对二乙苯的富液,然后采用萃取精馏的方法,选择一种有效的萃取剂,将间二乙苯和对二乙苯的分离系数增大,以提高分离效率,减少能耗,获得较高的纯度和收率。In this paper,taking the separat ion of m-diethenyl-benzene and p-die thenyl-benzene from C10heavy Aromatics as background for study.The o-dimethyl-phthatate was selected as the solvent for the separation of diethenyl-benzene preconcentrated from C10heavy Aromatics,by extractive ditillation,and the effect of the solvent was investigated by continuous distillation experiment.
