Abstract
The solubilities of anthracene and anthraquinone were measured in cycl ohexanone + carbon dioxide as a function of the temperature and pressu re of carbon dioxide at 291, 300, and 313 K and from 1.8-12.4 MPa. Ave rage equilibrium solubilities and recoveries of both solids increased with increasing normalized concentration and pressure. The average sep aration factor of anthracene to anthraquinone, due to the effect of th e mixed solvent, was 2.88 +/- 1.91.
