Solubility of erythromycin a dihydrate in different pure solvents and acetone + water binary mixtures between 293 K and 323 K

The solubility of erythromycin A dihydrate in pure ethanol, propan-2-ol, methanol, acetone, chloroform, and acetone + water was measured by a synthetic method at temperature ranging from 293.20 K to 323.00 K at atmosphere pressure. The laser monitoring observation technique was used to determine the disappearance of the solid phase in a solid + liquid mixture. The results of these measurements were correlated by a semiempirical Apelblat equation.
