Ionic liquid bonded on chitosan derivative (IL-b-CS) was synthesized by the reaction of 3-bromoalkyl-1-methyl imidazolium bromide with chitosan in the environmentally friendly water medium. The characterization of IL-b-CS was carried out by Fourier transform infrared spectroscopy (FT-IR), the nuclear magnetic resonance (NMR), X-ray diffraction (XRD) and the thermo gravimetric (TG), respectively. Using IL-b-CS as catalyst, the catalytic performance on the N-hydroxyl alkylation reaction of aromatic amine and ethylene carbonate under the solvent-free conditions was studied. Effect of the reaction conditions (for example: catalyst dosage, reaction material ratio, reaction temperature and reaction time etc.) on its catalytic activity was investigated in details.

Key words: ionic liquid, bonding, chitosan, preparation, catalysis
