摘　　要：应用UNIFAC基团贡献法,将N 甲酰吗啉(NFM)划分为一个基团,用实测的和文献公开发表的含NFM的芳烃和非芳烃的二元和多元汽液相平衡数据,采用最大似然函数法拟合关联出了CH2 NFM、ACH NFM、ACCH2 NFM、H2O NFM4对UNIFAC基团相互作用参数拟合误差较为满意,能够满足用N 甲酰吗啉萃取精馏精制苯工艺的工程计算的需要。N-Formylmorpholine(NFM) was divided into one group based on the UNIFAC model. The interaction parameters of UNIFAC model between CH_2-NFM?ACH-NFM?ACCH_2-NFM?H_2O-NFM were fitted by use of measured and published VLE data of aromatic and non-aromatic hydrocarbon system contained NFM. The deviation was satisfactory. The interaction parameters of UNIFAC model can be used in designing the process of refining benzene by extract-distillation with NFM as solvent.
