Viscosities [eta] of seven binary systems of n-propylamine, n-butylamine, n-hexylamine, n-octylamine, n-hexane, n-octane, and isoctane (2, 2, 4-trimethylpentane) with tributylamine have been measured at 303.15 and 313.15 K with an Ubbelohde suspended-level viscometer. Based on Eyring's theory, values of excess Gibbs energy of activation [delta]G[sup *E] of viscous flow have been calculated. Deviations of viscosities from linear dependence on the mole fraction and values of [delta]G[sup *E] are attributed to the H-bonding and to the size of alkylamine and alkane molecules. The free volume theory of Prigogine-Flory-Patterson in combination with work by Bloomfield-Dewan has been used to estimate the excess viscosity [delta]1n [eta] and the terms corresponding to enthalpy, entropy, and free volume contributions for the present binary mixtures. 25 refs., 7 figs., 7 tabs.
