Viscosities and densities of binary liquid mixtures of m-cresol with substituted anilines. Part 3

Densities and viscosities were determined for the binary systems of m-cresol with aniline, N-methylaniline, N, N-dimethylaniline, N-ethylaniline, and N, N-diethylaniline at five different temperatures. From the experimental results, the excess volume, excess viscosity, excess molar free energy of activation of flow, excess partial molar volume, and partial molar volumes were calculated. Also various thermodynamic parameters of activation of flow were 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.

Excess volume and viscosity of binary liquid acid–base mixtures

Densities, viscosities, and refractive indices at 25 °C were determined for the systems: o chlorophenol + N,N-dimethylaniline, o-chlorophenol + aniline, o-chlorophenol + m-toluidine, and o-chlorophenol + pyridine. From the experimental results the excess volume, excess viscosity, excess molar free energy of activation of flow, and the excess partial molar volume were calculated. There is evidence of complex formation between o-chlorophenol and the four bases.
