1 IntroductionIonic liquids(ILs) are environmentally acceptable solvents because they have low vapor pressure,high thermal stability and chemical stability,excellent solvent for organic and inorganic compounds.Therefore,they can be used as green solvents for a number of chemical processes,such as separations and reactions[1,2].ILs are also used as catalysts in chemical reactions to accelerate reaction rate and improve selectivity[3,4].
