Equilibrium solubilities of p-quinone (1,4-benzoquinone) and 9,10-anthraquinone at 35 C and 45 C in supercritical carbon dioxide over a pressure range of about (85--300) bar have been measured using a supercritical fluid extractor coupled with a high-pressure liquid chromatography apparatus. The solubility results, along with those reported in the literature for 1,4-naphthoquinone, are correlated with a modified Peng-Robinson equation of state. The ability of a supercritical fluid to separate a multicomponent mixture is unique, since it utilizes the salient features of both distillation and liquid extraction. The solubility of a solute in a supercritical fluid is the most important thermophysical property that has to be determined and modeled for an efficient design of any extraction based on supercritical solvents.
