✦ Synopsis

Solubilities of synthetic trans-b-carotene in supercritical carbon dioxide and ethane were measured, at temperatures from 35 to 60°C and pressures up to 300 bar, using a single-pass flow apparatus. The compound showed a low solubility in both solvents, but in ethane, its value was about an order of magnitude higher. The solubility measurements were compared with those published by other workers, which used different methods for the determination of the concentration of b-carotene in supercritical fluids. Moreover, the solubility data were correlated using the Peng-Robinson equation of state.

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 possibl
