ABSTRACT

Solubility of benzophenone in various pure solvents, including water, ethanol, propanol, isopropanol, methanol, butanol, isobutanol, octanol, acetonitrile, acetone, ethyl acetate, and acetone + water binary solvent, has been measured at temperature between 278.15 K and 318.15 K by a static analytic method under atmospheric pressure. Solubility obtained in various pure solvents and binary solvents both increase with rising of temperature. Several thermodynamic models, including modified Apelblat model, NRTL model, Wilson model, (CNIBS)/R-K model and Jouyban-Acree model, were applied to correlate the measured solubility. It was found that correlated results of the five models were in good agreement with the experimental results. In addition, the dissolution thermodynamic properties of benzophenone in different pure solvents, including dissolution enthalpy, dissolution Gibbs energy, and dissolution entropy were determined.
