Solubilities of Phenol and Pyrocatechol in Supercritical Carbon Dioxide

Abstract

The solubilities of phenol and pyrocatechol (1,2-dihydroxybenzene) in supercritical carbon dioxide were measured over the temperature range from 333.15 K to 363.15 K and the pressure range from 100 bar to 350 bar. The data were obtained using a recirculating equilibrium apparatus, which was tested by measuring the solubility of naphthalene in supercritical carbon dioxide. The measured solubilities were correlated using a semiempirical model proposed by Bartle.
