Solubilities of carvedilol (CVD) in binary mixtures of (ethanol + propylene glycol (PG)) at 298.2, 303.2, 308.2, and 313.2 K are reported. The modified versions of the van't Hoff and Gibbs equations were used to calculate the thermodynamic properties (enthalpy (ΔH°), entropy (ΔS°), and Gibbs energy (ΔG°) standard changes of solutions) for CVD dissolved in (ethanol (1) + PG (2)) mixtures from the solubility data. The solubility data of CVD in (ethanol (1) + PG (2)) at different temperatures were correlated using different mathematical models, i.e., the Jouyban−Acree model, a combination of the Jouyban−Acree model with the van't Hoff model, and two modified versions of the Jouyban−Acree model. Solubility data of seven drugs in (ethanol (1) + PG (2)) at different temperatures were used to develop a quantitative structure−property relationship model for predicting solubility in solvent mixtures. In addition, enthalpy−entropy compensation using ΔH°vs ΔG°a nd ΔH°vs TΔS°which explains the mechanism of cosolvency at different temperatures was discussed.

“…In order to consider both temperature and solvent composition of the binary solvent mixtures, the Jouyban‐Acree model was modified in conjunction with the modified Apelblat equation :

An online concentration monitoring method was established by using attenuated total reflection ultraviolet (ATR‐UV) coupled with a suitable partial least squares regression for a multi‐solute crystallization system, namely, disodium 5'‐inosinate (IMP) and disodium 5'‐guanylate (GMP) in aqueous ethanol. The results indicated that the established method accurately predicted the concentration of IMP and GMP in the solution. The solubility data was measured at various temperatures and ethanol/water mass ratios, and the experimental data was well correlated by applying the modified Apelblat equation and modified Jouyban‐Acree model. The implementation of cooling crystallization demonstrates that the developed calibration model is suitable for online concentration monitoring with reasonable accuracy and precision.
