Volumetric and viscometric studies of binary and ternary mixtures of nitrobenzene with 1,4-dioxane, benzene, toluene and carbon tetrachloride at 303.15 K

Abstract

Densities and viscosities of binary and ternary mixtures of nitrobenzene with 1,4-dioxane, benzene, toluene and carbon tetrachloride have been measured at 303.15 K. Viscosity deviations (An) and excess thermodynamic properties viz. excess molar volume (V E ) and excess Gibbs free energy of activation of viscous flow (ΔG #E ) have been calculated from experimental data in respect of binary and ternary mixtures at 303.15 K, and fitted by Redlich-Kister and Cibulka equations respectively. From the small magnitude of the values of standard deviation it is concluded that the experimental values of Δη, V E and ΔG #E compare fairly well with the corresponding theoretical values predicted by Redlich-Kister and Cibulka equations for binary and ternary mixtures respectively.
