摘要

The ability to predict the solubility of analytes in supercritical fluids is important in understanding supercritical fluid extraction (SFE) and supercritical fluid chromatography (SFC). In SFE, an analyte must dissolve in the supercritical solvent before it can be extracted. In SFC, the retention behavior of an analyte can be predicted once its solubility characteristics are known. Thermodynamic methods using a phase equilibrium approach have been used in the past to predict solubility in supercritical fluids. These methods usually involve complicated calculations and need some experimental data to compute unknown parameters. The authors have developed simple empirical methods for predicting solubility in supercritical fluids as a function of the prevailing temperature, pressure and density.
