摘要：

Equilibrium solubilities of m-nitrophenol, p-nitrophenol, 2,4-dinitrophenol, 2,5-dinitrophenol and picric acid at 308, 318, 328, 338 and 348 K in supercritical CO2 over a pressure range of 121.6-485.4 bar have been measured using a simple and reliable static method. The experimental data were correlated using a density-based model proposed by Chrastil. (C) 2002 Elsevier Science B.V. All rights reserved.
