摘要/描述

The solubility of 2-naphthol and anthracene in supercritical CO2 was determined at 308.1, 318.1 and 328.1 K, with and without cosolvent. The influence of three polar or nonpolar cosolvents, acetone, ethanol and cyclohexane, was studied at concentrations of 3.6 and 4.0 mol%. The solubility enhancement with these cosolvents is considerable, and the cosolvent effect increases in the order ethanol, acetone, and cyclohexane for 2-naphthol and for anthracene, the order is cyclohexane, ethanol, and acetone. The influence of density and cosolvent on the solid solubility was studied and discussed.
