실험 절차
N-ethoxymethyl-N-methylpyrrolidinium chloride (60.90 g) was mixed with a solution of hydrofluoric acid. N2 was bubbled through the mixture with heating at 60° C. to remove hydrogen chloride and an excess of hydrofluoric acid and obtain 62.10 g of N-ethoxymethyl-N-methylpyrrolidinium fluoride. In 1000 g of 50% aqueous solution of hydrofluoric acid was dissolved 156 g of aluminum hydroxide at room temperature and the mixture was filtered. The filtrate was cooled to obtain 442.76 g of aluminum fluoride nonahydrates. To 46.70 g of the above N-ethoxymethyl-N-methylpyrrolidinium fluoride was added 53.40 g of aluminum fluoride nonahydrates at 50° C. with stirring. N2 was bubbled through the mixture with heating at 130° C. to remove hydrofluoric acid and obtain 46.80 g of the desired product (brown liquid). The product was checked for 1H-NMR and electrical conductivity as in Example 1.
