1 Introduction Ionic 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 separa- tions and reactions. ILs are also used as catalysts in chemical reactions to accelerate reaction rate and improve selectivity.
