Two-fluid theory and thermodynamic properties of liquid mixtures: Application to simple mixtures of nonelectrolytes

AUTOR(ES)
RESUMO

In this last of three articles describing a two-fluid theory of liquid mixtures, the important result is a derivation of local compositions to describe nonrandomness (clustering) of mixing. The model is applied to the system methane/tetrafluoromethane. Although it appears that the two-fluid theory with local compositions may provide an improvement over random-mixing theories, it is likely that the use of local compositions overestimates the effect of nonrandomness.
