| Abstract: | Objective] The Solubility of Ferulic acid in supercritical carbon dioxide and its variation regulations were studied.Method]The solubility of ferulic acid in supercritical carbon dioxide was determined by dynamic method,and quantified by HPLC.Chrastil model and del Valle-Aguilera modified model were proposed to correlate and predict solubility in supercritical fluid.Result] Under the conditions of 10.0-30.0 MPa and 313.15-343.15 K,the mol fractions of the ferulic acid solubility were from 10-6 to 10-4.The AARD were 15.18% for Chrastil model and 7.003% for del Valle-Aguilera modified model.Conclusion] The modified solubility model proved to be more valid for solubility correlation of ferulic acid. |
