ABSTRACT

The density and kinematic viscosity of the binary systems (methyl pentanoate or methyl heptanoate) + 1-hexanol and octane + 1-hexanol were determined at (293.15, 303.15 and 313.15) K and atmospheric pressure over the whole concentration range. Moreover, the same properties were determined for the ternary systems (methyl pentanoate or methyl heptanoate) + octane + 1-hexanol at the same experimental conditions. The experimental binary and ternary viscosities were used to evaluate the applicability of several empirical and semi-empirical correlation models available in the literature. The excess volumes of the binary and ternary mixtures were compared to those predicted by the group-contribution model proposed by Nitta et al. using structural and energetic parameter sets previously reported in the literature. Also, viscosities were used to test the predictive capability of two group-contribution models (UNIVAC and UNIFAC-VISCO).
