Abstract:
In this work, UNIFAC group interaction parameters, (a_(CHO) ,COOH,a_(COOH),CHO);(a_(AcCH_2),CHO、a_(CHC),AcCH_2);(a_(Ac CH_2,COOH、aCOOE,AcCH_2),have been modified and supplemented, VLE of the binary systems of toluene-benzaldehyde, benzaldehyde-benzoic acid and toluene benzoic acid are calculated and the VLE of the ternary system is predicted by these pa rameters. The result is satisfactory.
