Comment on “Density, dynamic viscosity, excess property and intermolecular interplay studies for 1,4-butanediol + dimethyl sulfoxide binary mixture”

Abstract

A polemic is given regarding the calculated volumetric properties reported by Yue and coworkers for binary mixtures containing 1,4-butanediol and dimethyl sulfoxide. The calculated excess molar volumes reported by the authors for 293.15 K are not thermodynamically consistent with the calculated partial molar volumes of the mixture components. The calculated excess molar volumes at 293.15 K are negative, while the partial molar volumes suggest that the excess molar volumes should be positive. Thermodynamic inconsistencies were found at other temperatures as well.
