Partial molar volumes and compressibilities of metformin hydrochloride in aqueous-NaCl/sucrose solutions at 30 °C

Study of Excess Parameters and Partial Molar Volume for the Molecular Interactions of an aqueous 2-(tert-butylamino)-1-(3-chlorophenyl) Propan-1-one and NaCl Solution at Different Temperatures

“…5, excess intermolecular free length (L f E ) values are observed to be negative for the full mole fraction range of binary liquid mixutre. The negative trend of Lf E indicates the sturdy interactions between liquid mixtures and this is supported by the Kerr effect as well (Deosarkar, Tawde& Kalyankar, 2018).…”

“…The excess thermo-acoustic parameters, such as excess freely intermolecular (Lf E ), excess adiabatic compressibility (βE) and excess free volume (Vf E ), are calculated for the whole mole fraction range. An interpretation of these data shows that the interaction between drug and solvent dominate over interaction between the solute-solute (Deosarkar, Tawde, Kalyankar, 2018). Thus it may be concluded that the hydration sphere of the drug releases water molecules due to the electrolyte NaCl and solvent interactions.…”

“…These properties are dependent on molecular size as well as shape and the mixture-component interactions. The various excess molar properties for studied solutions were evaluated using the relation given below- (Deosarkar, Tawde& Kalyankar, 2018).…”
