摘要：

Entrainers have the potential of enhancing the solubility of a solute in a supercritical gas. Removing the entrainer from the supercritical gas, on the other hand, reduces the solubility. This effect may be used for separating solutes from a supercritical solvent. It will be shown, for example, that for the system CO2 and ethanol, it is advantageous to extract the ethanol in a countercurrent extraction with water, leading to a reduction in the solvent power of the gaseous phase. This was tested using a deodorizer condensate of soybean oil containing more than 55 wt% tocochromanols.
