ABSTRACT The Measurements of density, speed of sound and viscosity at different concentration of (S)-2-(2-oxopyrrolidin-1-yl) Butanamide drug in70% Ethanol-water, 70% Acetone-water and 70% DMF-water solutions at 308K. Acoustic parameter studies provide information in understanding molecular behavior and intermolecular interactions of (S)-2-(2-oxopyrrolidin-1-yl) Butanamide drug in solvent mixtures. From the experimental data various acoustical parameters such as apparent molar compressibility φk), apparent molar volume (φv), adiabatic compressibility (βs), specific acoustic impendence (Z), intermolecular free length (Lf) and relative association has been evaluated. The variation of these acoustic parameters is explained in terms of solute -solvent molecular interaction occurring in Drug solutions. Compressibility has been found to decrease with the increase in concentration for all compositions indicating the increase in ion-solvent interaction. The concentration range is 0.002 to 0.01 mol dm-3.
