چکیده انگلیسی
Solubility and thermodynamic data of apigenin (APG) in binary {2-(2-ethoxyethoxy)ethanol (Transcutol®) + water} mixtures were obtained in this work. The mole fraction solubilities (xe) of APG in binary {Transcutol®â¯+â¯water} mixtures were measured at temperature Tâ¯=â¯298.15â¯K to318.15â¯K and atmospheric pressure pâ¯=â¯0.1â¯MPa. Solubility values of APG determined in this study were fitted well with four different computational models namely “van't Hoff, Apelblat, Yalkowsky and Jouyban-Acree” models with root mean square deviations of <4.0%. The maximum xe value of APG was recorded in neat Transcutol® (0.382 at Tâ¯=â¯318.15â¯K). However, the minimum xe value of APG was recorded in neat water (1.01â¯Ãâ¯10â6 at Tâ¯=â¯298.15â¯K). The values of activity coefficients were also determined for the evaluation of solute-solvent molecular interactions and results suggested higher solute-solvent molecular interaction in APG-Transcutol in comparison with other combinations studied. Apparent thermodynamic analysis suggested endothermic and entropy-driven dissolution of APG in all binary {Transcutol®â¯+â¯water} mixtures studied. Enthalpy-entropy compensation analysis suggested enthalpy-driven mechanism as the main mechanism for solvation behavior of APG.
