A semi-theoretical relation for the excess Gibbs energy (GE)
developed previousl by Kreglewski et aL has been modified by
incorporating an association assumption, which includes the
expression developed earlier as a special case. The current
model successfully improves the representation of vapor-
liquid equilibria (VILE) for highly nonideal solutions,
especially for alcohol-hydrocarbon systems in the dilute
regions. It provides a good extrapolation for activity
coefficients at infinite dilution (y'), and reduces to the
original expression for simple systems. The temperature
dependence of its parameters also has been determined. The
current model can correlate vapor-liquid equilibria, heat of
mixing, and excess heat capacity data simultaneously. Based
upon an assumption relating ternary unlike molecular
interactions, the model can predict ternary VLE based solely
upon binary data. Data for different types of system
nonideality have been collected, evaluated and used to test
the ability of the model to describe the excess thermodynamic
properties of liquid mixtures of nonelectrolytes.
