Abstract

Viscosity and density data are presented for five binary liquid mixtures of acetonitrile with aniline and substituted anilines at five different temperatures. The experimental data are fitted to semitheoretical equations proposed by McAllister and Heric. Excess viscosity, excess volume and the excess Gibbs energy of activation of flow have been calculated from the experimental data. Various thermodynamic parameters of activation of flow are calculated from the dependence of viscosity on temperature. The deviations from ideality of thermodynamic and transport functions are explained on the basis of molecular interactions between the components of the mixture.
