| The equilibrium solubility of sulfadiazine (SD) in {ethylene glycol (EG) (1) + water (2)} mixtures at temperatures from (278.15 to 318.15) K is reported. Mole fraction solubility of SD (x3) increases with temperature arising and also increases with the EG proportion increasing. It varies from 4.81 × 10−6 in neat water to 5.32 × 10−4 in neat EG at 298.15 K. Solubility behavior was correlated by the extended log-linear model of Yalkowsky, the Jouyban-Acree model, and Jouyban-Acree-van't Hoff model and the obtained mean percentage deviations are 43.6%, 7.0% and 7.1%, respectively. From the variation of solubility with temperature the apparent thermodynamic analysis of dissolution and mixing was performed in all the mixtures and neat solvents. Based on the inverse Kirkwood-Buff integrals (IKBI) is observed that SD is preferentially solvated by water in water-rich mixtures (0.00 < x1 < 0.24) but preferentially solvated by EG in the interval (0.24 < x1 < 1.00). |
