| Abstract: | A flow method apparatus was built for determination of solid solubility in supercritical carbon dioxide.A sampling valve was used to obtain the sample,which was especially effective for the solids with less solubility.To test the system,the solubility of model solute naphthalene at 308K was determined.The experimental data are in agreement with literature values.The system works at temperature from 0 to 80℃ and pressure from 0.1 to 40MPa. |
