摘　　要：煤焦油洗油中分离产物在农药、医药、染料、加工助剂及工程塑料等领域有着广泛的应用。目前分离洗油中α-甲基萘、β-甲基萘、喹啉、联苯、吲哚、苊及芴等普遍采用精馏重结晶方法,该方法耗能大、污染大,因此研究探讨洗油加工中的绿色分离过程是十分有必要的。绿色分离过程的主要绿色分离方法有反应精馏、绿色溶剂流体萃取及膜过程。开发绿色分离工艺对于洗油深加工方面具有一定的科研价值和工业前景。The products separated from wash oil were widely used in pesticides,medicine,dye,processing aids and engineering plastics.Distillation and recrystallization of wash oil was the main separation method in α-methyl naphthalene,β-methyl naphthalene,quinoline,biphenyl,indole,acenaphthylene,fluorene etc,which is power-wasting and largely polluted.It＇s necessary to develop green separation process.In general green separation process includes reactive distillation,fluid extraction with green solvent and membrane process.The development of green separation is of research value for the further processing of wash oil and industrial application.
