【摘要】There are 1imited Vapor—Liquid Equilibrium(VLE)data including N-formylmorpholine(NFM )for the design of the extractive distillation process using NFM as solvent．The new interaction parametersof UNIFAC mode1 were fitted with experimenta1 data between CH2， ACH and NFM which was regardedas a main group．Comparison of the prediction results of VLE data and infinite dilution activity coefficientswith other published methods of group division for NFM ．indicated more satisfying results with theinteraction parameters of this paper．The four methods of group division for NFM were discussed based Onthe group division for ring molecule and group charge distribution．The group charge distribution at theminimum energy state was calculated by the AM 1 method in Chem3D Pro．The od theoretica1 basis Waspresented for the group division of NFM．
