Progress in ionic liquids for extraction of organic compounds
摘要
Abstract
Ionic liquids are described as “green solvents” since there is a large degree of cation/anion combinations which make them with the possibility of tuning their properties,as well as their very low volatility. Ionic liquids have been widely used in catalysis,separation and electrochemistry. Thereinto, ionic liquids have been regarded as an efficient extractant for extraction organic compounds. In this work,the ionic liquids used in the separate of hydrocarbon compounds,organic acids,alcohols, phenols and nature compounds by extraction were summarized and reviewed. The mechanism of the ionic liquids extraction process and the effect of extraction conditions were discussed in detail. It was concluded that the strong hydrogen bond,π-π,van der Waals and electrostatic interactions between ionic liquids and solute molecule make ionic liquids be potential solvents to replace some conventional organic solvents for the extractive separation of organic compounds. Meanwhile,the high viscosity and high costs as well as the recovery of the ionic liquids after extraction process could limit the industrial utilization of ionic liquids,and thus it is still an urgent task.关键词
