摘要：

Viscosities eta of dilute solutions of n-propylamine, n-butylamine, di-n-butylamine, and tri-n-propylamine in tetrachloromethane, n-propylamine, n-butylamine, di-n-propylamine, di-n-butylamine, tri-n-propylamine, and tri-n-butylamine in trichloromethane at 303.15 and 313.15 K and of triethylamine in 1,4-dioxane, ethyl ethanoate, butyl ethanoate, ethyl methyl ketone, chlorobenzene, and nitrobenzene have been measured at 303.15 K. The specific viscosities (eta - eta(s)(degrees))/eta(s)(degrees) and viscosity deviations Deltaeta have been calculated. Based on Eyring's theory of absolute reaction rates, values of excess Gibbs energy of activation DeltaG*(E) of viscous flow have been determined. The results have been analyzed in terms of Herskovits and Kelly equation (J. Phys. Chem. 77 (1973) 381-388) and Nakagawa equation (J. Mol. Liq. 63 (1995) 303-316). (C) 2004 Elsevier B.V.
