The solubilities of phanol and chlorinated phenols in supercritical carbon dioxide were measured at 36/sup 0/C (and 60/sup 0/C for phenol) and 78-246 atm in an apparatus consisting of two in-series, high-pressure equilibrium cells, fitted to a heated metering valve and Bourdon-type Heiss pressure gage. Saturated solutions exiting the cells were determined by weighing, and carbon dioxide was determined with a wet-test meter. Standard deviations were generally < 5% and typically 1-2% of phenol mole fraction values. The two isotherms obtained for phenol showed distinctly different solubility behavior, owing to the fact that phenol is a solid at 36/sup 0/C but a liquid at 60/sup 0/C, and the solubilities measured are for phenol in the supercritical-fluid phase. Applications of dense-gas extraction in the regeneration of activated carbon are discussed.
