Excess molar volumes of (methyl ethanoate + 1-chlorooctane + an n-alkane) ternary mixtures and their constituent binaries at 25°C

Abstract

Excess molar volumes, at the temperature 25°C and atmospheric pressure over the whole composition range, are reported for the following binary mixtures: methyl ethanoate + (n-octane, n-decane); methyl ethanoate + 1-chlorooctane; 1-chlorooctane + (n-heptane, n-octane, n-nonane, n-decane); and for the ternary mixtures methyl ethanoate + 1-chlorooctane + (n-heptane, n-octane, n-nonane, n-decane). The values of excess molar volumes were calculated from density and composition results. The excess volumes were utilized to test the multiproperty group-contribution model of Nitta et al. using parameter sets available in the literature. Experimental results from ternary mixtures have also been compared to predictions from several empirical and semiempirical models, which utilize, exclusively, results from binary mixtures.
