In this paper experimental data available in the literature on vapor-liquid equilibria, densities and excess molar volumes of dialkyl carbonate + n-alkane mixtures on broad temperature and pressure ranges have been used in order to test four equations of state (EoS): Soave-Redlich-Kwong (SRK), Peng-Robinson (PR), Patel-Teja (PT) and Dohrn-Prausnitz (DP). For the pure components, when the critical parameters were not available in the literature, the group contribution method of Klincewicz and Reid was used to estimate the critical temperature and pressure. For dialkyl carbonate + n-alkane mixtures we have determined the binary interaction parameter, k(ij), using experimental vapor-liquid equilibria data and then with these parameters the pVTx values were predicted. The best correlations for VLE and predictions for the volumetric behavior were obtained with PR and PT equations. (C) 2003 Elsevier B.V. All rights reserved.
