Studies of viscosities of dilute solutions of alkylamine in non-electrolyte solvents. II. Haloalkanes and other polar solvents

Viscosities η 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 image and viscosity deviations Δη have been calculated. Based on Eyringʹs theory of absolute reaction rates, values of excess Gibbs energy of activation ΔG*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).
