| Abstract: | In the paper,the process simulation software,Aspen Plus was used to simulate the separation of ethyl acetate and n-hexane from the waste liquid in the pharmaceutical process by extractive distillation,and N-methyl-2-pyrrolidone（NMP） was used as extractive agent.The effect of theory stage,feed location,reflux ratio and ratio of extractive agent on the separation were detailed analyzed.The optimal conditions is found,which can be provided for the design and operation of the separation in its industrial production. |
