Thermodynamic properties of (a methyl ester + an n-alkane). V

Abstract

Excess molar enthalpies and excess molar volumes for six mixtures: {a methyl ester (from ethanoate to heptanoate) + tetradecane} have been determined at T = 298.15 K as a function of the mole fraction. All the mixtures studied exhibit positive values for both quantities which decrease quasi-exponentially with length of the methyl-ester chain. Several theoretical models were used to obtained the excess quantities, but the Flory and Nitta et al. models predict the excess molar volumes only poorly. © 1993 Academic Press Ltd.
