Supercritical fluid technology (SFT) as a new technique is very important for clean environment and removal of chemical pollutants. The lack of solubility data of solid solute in certain supercritical fluid is a great obstacle to the successful implementation of SFT. In this work, the solubility of bisphenol A in supercritical carbon dioxide was determined by the dynamic method at the temperatures ranging from 308 to 328 K and pressure range of 11.0-21.0 MPa. The effects of temperature and pressure on solubility were analyzed according to molecular motion theory. The solubility data were correlated using eight different semi-empirical models (Chrastil, Adachi-Lu, Kumar-Johnston, Tang, Sung-Shim, Bartle, Mendez Santiago-Teja and Yu). The comparison between different models was discussed. The thermodynamic properties (total enthalpy Delta H, enthalpy of sublimation Delta H-sub and enthalpy of solvation Delta H-solv) of the solid solute were obtained.
