ABSTRACT
The solubilities of betulin in acetone + water and ethanol + water were measured at T ) (278.2, 288.2, 298.2, 308.2, and 318.2) K. The solubilities of betulin in the two mixed solvent systems increase significantly with temperature and composition of acetone or ethanol. The Apelblat equation was used to correlate the experimental data.
