Examples
synthesis example 1
[0050]In a flask equipped with a refluxing column were charged 19.1 g (0.10 mol) of 1-ethyl-3-methylimidazolium bromide and 20 ml of water, and further 21.9 g (0.10 mol) of potassium salt of bis(fluorosulfonyl)imide, followed by stirring at 40° C. for 5 hours. After the reaction, 80 ml of methylene chloride was added, followed by well stirring and fractionating. The methylene chloride layer was washed five times each with 40 ml of water, and the methylene chloride layer is concentrated under reduced pressure to give 23.8 g (0.08 mol, yield: 81.8%) of 1-ethyl-3-methylimidazolium bis(fluorosulfonyl)imide.
synthesis example 2
[0051]The same procedure as the above Synthesis example 1 excepting using 20.5 g of 1-methyl-3-propylimidazolium bromide in place of 19.1 g of 1-ethyl-3-methylimidazolium bromide was conducted to give 27.5 g (0.09 mol, yield: 90.1%) of 1-methyl-3-propylimidazolium bis(fluorosulfonyl)imide. Viscosity of this compound was 29 mPa·s (25° C.).
synthesis example 3
[0052]The same procedure as the above Synthesis example 1 excepting using 20.5 g of 1-methyl-3-isopropylimidazolium bromide in place of 19.1 g of 1-ethyl-3-methylimidazolium bromide was conducted to give 27.1 g (0.09 mol, yield: 88.8%) of 1-methyl-3-isopropylimidazolium bis(fluorosulfonyl) imide. Viscosity of this compound was 27 mPa·s (25° C.).
