실험 절차
Diphosphorus pentoxide (reagent, produced by Wako Pure Chemical Industries, Ltd.) (2.8 g) was weighed into a 250 ml-volume PFA vessel, and 5.7 g of 1-butyl-3-methylimidazolium hexafluorophosphate (reagent, produced by Wako Pure Chemical Industries, Ltd.) was added. Subsequently, 14.0 g of a dimethyl carbonate solution of 10% hydrogen fluoride was added, and the mixture was refluxed at 110° C. for 1 hour while flowing nitrogen. Thereafter, the reaction solution was heated at 130° C. for 17 hours, thereby distilling off the excess solvent and reaction by-products, and then cooled to room temperature to obtain 1-butyl-3-methylimidazolium difluorophosphate. Anion analysis was performed in the same manner as in Example 1-1, as a result, the purity of the obtained 1-butyl-3-methylimidazolium difluorophosphate was 92% in terms of the relative area.
