ABSTRACT

Densities and viscosities of glycine, l-alanine, l-valine, l-threonine, and l-arginine in aqueous solutions of (0.0, 0.2, 0.4, 0.6, 0.8, and 1.0) mol*kg 1 mannitol have been measured in the temperature range of (293.15 to 323.15) K under atmospheric pressure; then the measured densities and viscosities of experimental systems were correlated. These data were further used to calculate the apparent molar volumes (Vf), the limiting partial molar volumes (Vf0), the limiting partial molar volumes of transfer (?trVf0), the viscosity B-coefficients, and the free energies of activation per mole of solvent (?micro10?) and solute (?micro20?). The results were interpreted through solute solute interaction and solute solvent interaction on the basis of the cosphere overlap model and transition state theory.
