反応手順
Analogously to Example 1, 26.5 g (0.152 mol) of 1-butyl-3-methylimidazolium chloride are reacted with 21.4 g of approx. 70% aqueous methanesulfonic acid, CH3SO3H. 100 ml of 1,4-dioxane are subsequently added, and 107 ml of HCl-containing water/dioxane azeotrope are distilled off at atmospheric pressure (85-101° C.). After 18 additional azeotropic distillations with 100 ml of 1,4-dioxane each time and drying of the distillation residue under reduced pressure at 1.3 Pa and 80° C., 1-butyl-3-methylimidazolium methylsulfonate is obtained. The yield is approximately quantitative.
