Thermophysical properties of binary liquid mixtures of tetrahydrofuran with benzene and substituted benzenes at 308.15 K

Densities (ρ) and viscosities (η) have been measured at 308.15 K over the entire composition range of binary mixtures of Tetrahydrofuran (THF) with benzene (B), methyl benzene (MB), ethyl benzene (EB), chloro benzene (CB), bromo benzene (BB) and nitro benzene (NB). This measured data have been utilized to calculate excess molar volume (VE), excess viscosity (ηE) and excess gibbs free energy for activation of viscous flow (G*E) and Grunberg-Nissan interaction parameter (d1). The values of these excess functions are fitted to the Redlich Kister equation. The results were discussed in terms of the existence of intermolecular interactions between the components in the liquid mixtures under study.
