Volumetric and viscometric studies of binary and ternary mixtures of o-nitrotoluene with methyl alcohol,benzene,toluene,carbon tetrachloride and 1,4-dioxane at 298,15 K

摘要

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.From 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 ternary liquid mixtures at 298.15 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 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 ternary mixtures respectively.
