반응 단계
86.3 g (0.494 mol) of 1-butyl-3-methylimidazolium chloride and 94.9 g (0.499 mol) of toluenesulfonic acid monohydrate are dissolved in 50 ml of 1,4-dioxane at RT. 58 ml of HCl-containing water/dioxane azeotrope are subsequently distilled off at atmospheric pressure (85-101° C). After 22 additional azeotropic distillations with 200 ml of dioxane each time and drying of the distillation residue under reduced pressure at 1.3 Pa and 80° C., 1-butyl-3-methylimidazolium tosylate is obtained. The yield is approximately quantitative.
