摘　　要：逆流解离萃取通过套用萃取酸分离间氯苯胺及对氯苯胺。该法可以解决错流解离萃取造成的酸消耗量大,废水多的问题,处理成本低,效益好,具有工业化的可行性。The separation of m-chloroaniline and p-chloroaniline was carried out by countercurrent dissociation extraction(CDE). This method solve the problems of high consumption of extractive acid and great amount of waste water, which were caused by alternative extraction. This method of CDE possesses the advantages of low cost and high profit and can be industrialized.
