実験手順
First, 6 ml of 99.7% acetic acid was added to 10 g of N-ethylimidazole, and the resultant mixture was stirred for 12 hours at a temperature kept at 0° C. The resultant reaction product was added dropwise to 1000 ml of diethyl ether under stirring. The diethyl ether was distilled off at room temperature, and the residue was dried under vacuum to precipitate crystals. The precipitated crystals were recovered to obtain 15.9 g of N-ethylimidazolium acetate. The product had a glass transition temperature of −51.7° C.
