Abstract: | Viscosities of three non-electrolyte binary mixtures have been determined at different temperatures over the complete concentration range. Excess molar viscosities and excess molar energies of activation for viscous flow for n-butylamine + dichloromethane, n-butylamine + chloroform and n-butylamine + carbon tetrachloride systems at 20°C, 25°C, 30°C and 35°C were calculated. Thermodynamic effect parameters of activation were also calculated. The predictive abilities of some equations for viscosities of mixtures were examined.Presented at the XV Jornadas sobre Investigación en Ciencias de la Ingeneriía Química y Química Aplicada, Neuquén, 1989, R.
