Abstract
The solubility of perfluoropentanoic acid in supercritical carbon dioxide was investigated for a broad range of pressures (10 to 26 MPa) and at three temperatures: 314, 324, and 334 K. A dynamic gravimetric device was used for the high pressure measurements. The solubility ranges from (24.7 +/- 0.3) kg.m(-3) at 334 K to 10.2 MPa to (103.9 +/- 7.7) kg.m(-3) at 314 K and 20.1 MPa. Density-based models, notably the dimensionless version of the Adachi-Lu model, fit the experimental data accurately. The latter model was employed to calculate the solubility over a wide range of CO2 densities.
