摘要：Solubility of α -asarone in supercritical carbon dioxide was measured and calculated by P-R equation and Chrastil method. Compared with experimental data, the average relative deviation of the calculated solubility of α -asarone is 25% and 8% for P-R equation and Chrastil method respectively,which indicates that the experimental results can be correlated well with Chrastil method.The Chrastil equation for the solubility of α -asarone in supercritical carbon dioxide was subsequently given, which can be applied to the prediction of solubility according to the practical supercritical conditions.
