作者： ZHANG Jun-li CHEN Xiao-rong yu Yan-peng xu Kun-ling HUANG Jun State Key Laboratory of Materials-Oriented Chemical Engineering College of Chemistry and Chemical Engineering Nanjing University of Technology Nanjing 210009 P. R. China

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.
