摘      要：The critical properties of binary mixtures are predicted using a theoretical alternative to the conventional mixing rules for the contribution of the attractive equation of state parameter for the mixture. The method does not require adjustable combining rule parameters and the only experimental input data are the critical properties of the component pure substances. The comparison of calculated critical properties with experimental data yields very good agreement. The discrepancy between theory and experiment is often similar to that obtained by using optimized adjustable combining rule parameters. Consequently, genuinely accurate a priori predictions of critical equilibria are possible for many binary mixtures containing either non-polar or weakly polar components.
