EQUATION OF STATE FOR MIXTURES CONTAINING POLAR COMPOUNDS

The new equation of state proposed by Brandani et al. has been extende d to mixtures, and appropriate mixing rules have been used for the par ameters. Three adjustable binary parameters have been used to fit the experimental data of 13 binary mixtures containing at least one polar compound, with the exception of the system carbon dioxide-n-butane. Th e results of the fitting are satisfactory. When applied to a ternary m ixture, predicted and experimental compositions of the liquid and vapo r phase agree very well.
