Abstract
The viscosities of 18 binary mixtures of ethanol, 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, 1-heptanol, 1-octanol, 1-nonanol, 1-decanol, 1-dodecanol, 2-propanol, 2-butanol, 2-pentanol and 2-octanol with cyclohexane and of 1-butanol, 1-pentanol, 1-hexanol and 1-heptanol with methylcyclohexane have been measured at 303.15 K over the entire range of composition. The viscosity deviations Îη and excess Gibbs energy of activation ÎG*E of viscous flow have been analyzed in terms of change in the structure of pure component molecules and molecular interactions. The results obtained for dynamic viscosity of binary mixtures were used to test the semi-empirical relations of Grunberg-Nissan, Katti-Chaudhri, McAllister and Auslaender.
