Enthalpies of mixing for the n-pentane + methylacetate + dichloromethane system at 298.15 K and their prediction with the UNIFAC model

Abstract

New experimental data of the excess molar enthalpies at 298.15 K for the ternary system n-pentane+methylacetate+dichloromethane, together with corresponding data for the constituent binary mixtures, are presented. Different expressions from the literature are used to predict excess enthalpies from the corresponding binary data. The empirical correlation of Nagata and Tamura (J. Chem. Eng. Data, 33 (1988) 283) gives 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.
