Abstract
The densities () and kinematic viscosities (ν) which was converted to the absolute viscosity () from the product of the kinematic viscosity and the density of L-Glutamine have been measured at different temperatures 298.15, 303.15 and 313.15K in aqueous 20% (w/w) dimethyl formamide (DMF) under atmospheric pressure. The value of apparent molar volume (v), limiting apparent molar volume (v ) and viscosity data have been analyzed by using Jones-Dole equation, the Jones-Dole coefficients (A and B) were calculated and excess Gibbs free energy of activation of viscous flow (〖〗^) has been obtained to throw light on the mechanism of viscous flow. The results were interpreted strong ion-solvent interactions in these systems and also structure-maker in 20% DMF + 80% water mixed solvents.
