Densities, viscosities and thermodynamic excess properties of ternary liquid mixtures of aniline + acetone + (benzene or + toluene or + carbon tetrachloride or + 1,4-dioxane) and their constituent binaries at 298.15 K

Abstract

Densities and viscosities of ternary liquid mixtures of aniline + acetone + (benzene or + toluene or + carbon tetrachloride or + 1,4-dioxane) and their constituent binary mixtures, viz. aniline + acetone, aniline + benzene, acetone + benzene, aniline + toluene, acetone + toluene, aniline + carbon tetrachloride, acetone + carbon tetrachloride, aniline + 1,4-dioxane, acetone + 1,4-dioxane have been measured at 298.15 K over the entire composition range. The values of viscosity deviations (Δη) and thermodynamic excess properties viz. excess molar volume (V E ) and excess Gibbs free energy of activation of viscous flow (ΔG #E ) have been determined for binary and ternary liquid mixtures at 298.15 K and fitted by Redlich-Kister and Cibulka equations respectively. It is concluded that 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 liquid mixtures respectively.
