| Abstract: | The infinite dilution activity coefficients of benzene or alkane in the solvent N Formylmorpholine(NFM) and the vapor liquid equilibrium of the binary system benzene NFM were predicted by the UNIFAC group contribution method.In addition ,interaction parameters of UNIFAC were modified to prove the precision of prediction. |
