چکیده انگلیسی
The densities Ï, and viscosities η, of pure toluene, cyclohexane, and n-hexane and those of their binary and ternary mixtures have been measured at 298.15 K and atmospheric pressure over the entire range of compositions. Excess molar volumes V123E, viscosity deviations Îη123, and excess Gibbs energy of activation G123*E, were obtained from the experimental results and those values for the binary and ternary systems were fitted to Redlich-Kister's and Cibulka's type function in terms of mole fractions. The V123E data were positive and Îη123 and G123*E, values were negative. Several semi-empirical relations are used to predict the ternary excess molar volumes and viscosity deviations from experimental results on the constituted ternary and analyzed to discuss the nature and strength of intermolecular interactions in these mixtures.
