Progress in application of ionic liquids in chemical separation process

Ionic liquids have great potential as excellent green solvents with novel functions as well as replacements for volatile organic solvents. These organic salts have been attracting more and more attention recently. Progress in application of ionic liquids in chemical engineering separation process was summarized, which referred to the extractive separation of bio-produets, metal ions, aromatic compounds, sulfur and nitrogen compounds from oil products, the extractive separation of sulfur and nitrogen compounds from liquid fuel, desulfurization of flue gas and gas separation processes. The progress in theoretical research of ionic liquids in phase equilibrium was summarized briefly, which pointed out that the current work was targeted on the regeneration of ionic liquids, the phase equilibrium, the separation mechanism, and the molecular design theory in order to speed up the commercial application of ionic liquids.
