ENTHALPIES OF MIXING FOR THE N-PENTANE PLUS METHYLACETATE PLUS DICHLOROMETHANE SYSTEM AT 298.15 K AND THEIR PREDICTION WITH THE UNIFAC MODEL

New experimental data of the excess molar enthalpies at 298.15 K for t he ternary system n-pentane + methylacetate + dichloromethane, togethe r with corresponding data for the constituent binary mixtures, are pre sented. Different expressions from the literature are used to predict excess enthalpies from the corresponding binary data. The empirical co rrelation of Nagata and Tamura (J. Chem. Eng. Data, 33 (1988) 283) giv es the best results for this system. The UNIFAC group contribution is applied to predict ternary excess molar enthalpies which are compared with the experimental data.
