Volumetric and Transport Properties Of L-Isoleucine In Aqueous Ethanol

A.B. Nikumbh, G.K. Kulkarni


Densities and viscosities of L- isoleucine have been measured at 298.15, 303.15, 308.15, 310.15 and 313.15 K in aqueous ethanol mixtures (wt.) % mass of ethanol. The viscosity data have been analyzed using the Jone-Dole equation. Apparent molar volumes, limiting partial molar volumes and relative viscosity have been evaluated from the density and viscosity data. Transfer volumes, limiting partial molar volumes and hydration numbers have also been calculated. The results have been discussed in terms of solute-solute and solute- solvent interactions and the structural changes of the solutes in solutions.

Key words: L-isoleucine, Molar volume, Molecular interaction, Density, Viscosity.
