摘要
Equilibrium solubilities of pure anthracene at 50 degrees C, 1-naphthol at 35, 45, and 55 degrees C, and hydroquinone at 35 and 45 degrees C in supercritical carbon dioxide over a pressure range of about 85-300 bar have been measured using a supercritical fluid extractor coupled with an external high-pressure liquid chromatographer. The solubility results, along with those for other phenols reported in the literature, are correlated with the translated-modified Peng Robinson equation of state.
