Abstract

•Experimental data of ρ, nD and η of binary systems with MEK.•Viscosity modeling with friction theory.•Viscosity correlation by Eyring-UNIQUAC, Eyring-NRTL, Teja-Rice, Grunberg-Nissan and McAlister equations.•New UNIFAC-VISCO and ASOG-VISCO parameters determinations.

In this paper densities, viscosities and refractive indices of four binary mixtures containing methyl ethyl ketone, at atmospheric pressure and in the temperature range from 288.15 K to 333.15 K are reported. From experimental measurements excess molar volumes, viscosity deviations and refractive index deviations are calculated and fitted to the Redlich–Kister equation. For the analysis of molecular interactions present in the mixtures, molar excess Gibbs free energies of activation of viscous flow are also calculated and fitted to the Redlich–Kister polynomial equation. Experimental viscosity data are modeled by friction theory, predictive UNIFAC-VISCO and ASOG-VISCO models and correlative Teja-Rice, Grunberg–Nissan, McAlister, Eyring-UNIQUAC and Eyring-NRTL models. The new CO–CH2O and CO–pyridine interaction parameters are determined for their application in the UNIFAC-VISCO and ASOG-VISCO models.
