| Abstract: | A set or equipment, using static method to determine the solubility or solid matters in supercritical carbon dioxide(SCCO_2), was established. The equilibrium solubility or ginger oil in the SCCO_2 was determined. In this paper, the ginger oil was classified into four components. The solubility of the these components was correlated with the densities and temperatures of the carbon dioxide. The correlation provided scientific basis for the extraction and separation technology. |
