Abstract: Viscosities of dilute solutions of n-propylamine, n-butylamine, di-n-propylamine, di-n-butylamine, tri-n-propylamine and tri-n-butylamine in toluene, and of tri-n-butylamine in benzene, have been measured at 303.15 K. The values of viscosity deviations are negative for all the amine solutions and their magnitude increases with the increase in concentration of alkylamine. The specific viscosities and excess Gibbs energy of activation of viscous flow, based on Eyring's theory of absolute reaction rates, are of varying magnitude and sign depending upon the viscosities and type and nature of solute and solvent molecules. The specific viscosities have been analyzed in terms of Herskovits and Kelly equation and Nakagawa equation. The change in Gibbs activation energy and the heat of solution per mole of solute (alkylamine) at infinite dilution in cyclohexane, benzene and toluene solutions have been calculated in terms of the transition state theory.
