✦ Synopsis

The solubility of phenylacetic acid and vanillan in supercritical carbon dioxide were measured at 308.15 and 3 18.15 K over a pressure range of 80 to 200 bar. The applicability of several density-based correlations and the Peng-Robinson equation-of-state to the data obtained is examined. The possible effects of both the carboxylic acid and hydroxyl groups on solubility behavior are also discussed.
