ABSTRACT

The densities, viscosities, refractive index, conductanceand surface tension of L-phenylalanine and L-tryptophan in aqueous Benzyltributylammonium chloride (BTBACl)solutions have been measured at 298.15K, 303.15K and 308.15K. Apparent molar volumes and viscosity B-coefficients are obtained from these data supplemented with densities and viscosities, respectively. The limiting apparent molar volumes and experimental slopesderived from the Masson equation have been interpreted in terms of solute-solvent and solute-solute interactions, respectively. The viscosity data have been analyzed using the Jones-Dole equation, and the derived parameters B and A have also been interpreted in terms of solute-solvent and solute-solute interactions, respectively. The structure making/breaking capacities of the solutes in the studied solvent systems have been discussed. Lorentz-Lorenz equation was used to calculate the molar refraction. The specific conductance and surface tension values also explained and supported the interaction properties.
