| Abstract: | The intermediate 1 butul 3 methylimidazolium bromide was synthesized from N-methylimidazolium and 1 bromobutane in the experiment, besides the effects by reaction temperature, time and molar ratio of materials were investigated. The optimum conditions were found to be ： the molar ratio of lbromobutane and N methylimidazolium being 1.1：1, temperature being at 70℃, time being 24h. In such environment after anion exchange, 1 butul 3 methylimidazolium tetrafluoroborate ionic liquid can be obtained and the structures of products were characterized by IR and ^1H NMR. |
