| Abstract: | The ionic liquids/sc-CO 2 system were introduced in this article. Ionic liquids and sc-CO 2 have been paid much attention due to their unique properties and environmental benignity. The combination of them has given out many new merits on reactions and separations. Supercritical CO 2 is very soluble in ionic liquids, and can extract the non-volatile products from ionic liquids. Since the ionic liquids and the catalysts dissolved in ionic liquids are insoluble in the sc-CO 2 phase, their loss in the process can be eliminated. Therefore, the ionic liquids/sc-CO 2 system could be used for environmental benign processes with good reaction-separation performance. |
