Volumetric and viscometric studies of binary and ternary miixtures of o-nitrotoluene with methyl alcohol, benzene, toluene, carbon tetrachloride and 1,4-dioxane at 298.15 K

Densities and viscosities of binary and ternary mixtures of o-nitrotoluene with methyl alcohol, benzene, toluene, carbon tetrachloride and 1,4-dioxane have been determined at 298.15 K over the whole composition range. Front density and viscosity data, viscosity deviations (Delta eta) and excess thermodynamic functions, viz. the molar volume (V-E) and the excess Gibbs free energy of activation of viscous flow (Delta G(#E)) have been calculated in respect of binary and tertiary liquid mixtures at 298.15 K and fitted by Redlich-Kister and Cibulka equations respectively. Front the small magnitude of the values of standard deviation it is concluded that the experimental values of Delta eta, V-E and Delta G(#E) compare fairly well with the corresponding theoretical values predicted by Redlich-Kister and Cibulka equations for binary, and tertiary mixtures respectively.
