摘要：
Excess molar enthalpies of the ternary system (x(1) (propylpropanoate) + x(2)(cyclohexane) + (1 - x(1) - x(2))benzene) and of their binary mixtures (x(1)(propylpropanoate) + x(2)(cyclohexane)) and (x(1)(cyclohexane) + x(2)(benzene)) have been determined at 298.15 and 308.15 K and atmospheric pressure, over the whole composition range. The excess molar enthalpies were measured using a Calvet microcalorimeter. The experimental values were compared with the results obtained with empirical expressions for estimating ternary properties from binary data. The group contribution model of UNIFAC in the version of Gmehling were also applied to predict excess molar enthalpies. (C) 2001 Elsevier Science B,V. All rights reserved.
