The solubility of alpha-asarone in supercritical CO2 (sc-CO2) has been measured using the dynamic method. The measurement was conducted in the pressure range from 9.0 to 18.0 MPa at temperature 35-49 degreesC. The experimental data were correlated using the Chrastil model. The results show that the solubility increases as the pressure rises and decreases as the temperature rises, which is well correlated with the Chrastil model. (C) 2003 Elsevier B.V.
