Solubilities of methoxybenzoic acid isomers in supercritical carbon dioxide

The solubilities of methoxybenzoic acid isomers in supercritical carbon dioxide were measured using semiflow phase equilibrium apparatus at temperatures ranging from 308.2 to 328.2 K over a pressure range of 99.6–246.9 bar. The measured solubilities were correlated using three empirical equations. The calculated results indicate good agreement with the experimental data.
