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 × 10–2), ethanol (2.58 × 10–2), n-propanol (2.39 × 10–2), and isopropyl alcohol (6.72 × 10–3) was significantly higher than in acetone (2.58 × 10–4) and ethyl acetate (8.02 × 10–5) at 298.15 K. The experiment data would be useful for optimizing purification and recrystallization processes of dl-PHPB in industry.
