The solubility of racemic potassium 2-(1-hydroxypentyl)-benzoate (dl-PHPB) in methanol, ethanol, n-propanol, isopropyl alcohol, ethyl acetate, and acetone from 298.15 to 333.15 K was measured by an equilibrium method. The solubility data of dl-PHPB in six different solvents was correlated by the modified Apelblat equation. The correlation coefficients were observed in the range of 0.993 to 0.998, indicating a good fit. The results showed that the mole fraction solubility of dl-PHPB in methanol (6.22 X 10(-2)), ethanol (2.58 X 10(-2)), n-propanol (2.39 X 10(-2)), and isopropyl alcohol (6.72 X 10(-3)) was significantly higher than in acetone (2.58 X 10(-4)) and ethyl acetate (8.02 X 10(-5)) at 298.15 K. The experiment data would be useful for optimizing purification and recrystallization processes of dl-PHPB in industry.
