ABSTRACT

The equilibrium solubility of hesperidin in cosolvent mixtures of ethanol (1) + water (2), isopropanol (1) + water (2), propylene glycol (1) + water (2) and n-propanol (1) + water (2) were determined experimentally by using the static method within temperature range from (293.15 to 333.15) K under atmospheric pressure of 101.1 kPa. The hesperidin solubility increased monotonously with increasing temperature and mass fraction of ethanol (isopropanol, propylene glycol and n-propanol). At the same temperature and mass fraction of alcohol, the mole fraction solubility of hesperidin was greater in (propylene glycol + water) than in the other three cosolvent mixtures. The solubilities of hesperidin in the four cosolvent mixtures were mathematically represented by using the Jouyban-Acree model, van't Hoff-Jouyban-Acree model and Apelblat-Jouyban-Acree model obtaining average relative deviations lower than 2.38 % for correlative studies.
