Preparation of supported ionic liquids catalyst and its catalytic performance

Some different supported ionic liquids (ILs) catalysts, such as physical adsorption supported ILs catalyst, silica gel confined ILs catalyst and covalently supported ILs catalyst, were introduced, and the characterization techniques for supported ILs catalysts, such as low-temperature nitrogen adsorption-desorption technique(BET), transmission electron microscope(TEM), X-ray diffraction(XRD), differential scanning calorimetry(DSC), thermogravimetric thermal analysis(TGA), Fourier infrared spectroscopy(FT-IR), nuclear magnetic resonance(NMR) and so on. The application of ILs in hydrogenation reaction, selective oxidation, carbonylation and hydroamination reaction, were investigated. Finally, the further research and development of supported ILs catalysts were prospected.
