【Abstract】 The solubilities of 2-hydroxybenzoic acid were measured in supercritical carbon dioxide with and without en-trainers at the range of temperature of 308.15 K and 328.15 K, and pressure of 10.0-25.0 MPa. Based on the analysis of mechanism of the entrainer effect on the solid solubilities in supercritical fluids, the fundamental principles to select entrain-ers were proposed .更多还原
