✦ Synopsis

Ah&w--The new equation of state proposed by Brand& er ul. has been extended fo mixtures, and appropriate mix& nil= have bsen uzxxl for the parameters. Th= adjustable binary parameters have ken used to fit the experimental data OC 13 binary mixtures containing at least one polar compound, with the exception of the system carbon dioxidcn-butane. The results of the fitting are satisfacrory. Wbcn applied to a ternary mixture, predicted and experimental wmpositions of the liquid and vapor phase agree wry well. 1. INTRODUCTTON ReccntIy, a new equation of state, particularly suitable for pure polar compounds, has ticen proposed by Brandani er aI. (1992, 1993) In this work this new equation of state has been extended to mixtures using appropriate mixing rules for the parameters. The new equation of state has ken employed to fit VLE data of binary mixtures and to predict the behavior of a ternary mixture.
