Abstract: Based on the group interaction parameters determined from binary VLE data,the VDW-GC EOS developedin Part I~[13] is extended to binary and multicomponent liquid-liquid equilibrium calculations.Equilibrium phasecompositions and the temperature effects on LLE can be predicted with reasonable accuracy.
