英文摘要：

Two carboxyl- and hydroxyl- functionalized ionic liquids, 1-earboxybutyl-3-methylimidazolium bromide and 1- hydroxyethyl- 3- methylimidazolium bromide, were designed and synthesized. On this basis, the chemical composition of these ionic liquids was characterized by infrared spectra and nuclear magnetic resonance spectroscopy. All the corresponding chemical shifts and wavenumbers of peaks were consistent with theoretical values. No impurity peaks were found in the spectra. According to the experimental results, all these ionic liquids had high purity and quality. It was expected that present work will provide important scientific foundation for the relevant research and application.
