As novel green solvents, ionic liquids have wide application potential in oil industry. Many kinds of small organic molecules, biological molecules and metal ions have good solubility in ionic liquids. Moreover, due to its advantages of non-volatility, wide range of fluidity and tunable solvation property, it can be used for separation and enrichment of lipid instead of some traditional organic solvents. Advance in application of ionic liquids in separation and enrichment of lipid were summarized, including the property of ionic liquids, the extraction effect of microalgae oil, the separation and enrichment effect of components in oil, the enrichment effect of the risk substances in oil. In the end, the future research prospects of ionic liquids in lipid separation and enrichment were prospected. |
