摘要：

Using a flow-type apparatus for supercritical fluid extraction, solubilities of an alcohol in supercritical CO2 have been measured at 313 K and 333 K up to 11 MPa. Ethanol, 1-propanol, 2-propanol and 1-butanol were selected as the alcohols. Consistency of the obtained solubility data was tested by the enhancement factor method, which showed good consistency for all systems. The logarithmic values of the enhancement factors for all the alcohols were observed to be linear functions of pure CO2 density. Employing this linear relationship, the solubility of an alcohol in supercritical CO2 can easily be determined with high accuracy.
