Example 5; [TMA][ise]; [TMA][ise] is an ionic liquid comprised of tetramethylammonium (TMA) as the cation, and isethionate (ise) as the anion. In a manner similar to Example 3, a 1-neck round bottom flask holding an aqueous solution of [TMA][OH].5 H2O (9.094 g, 50 mmol) was fitted with a pH probe such that the probe extended below the level of the batch. The pH was adjusted from 14.68 to 5.49 by the addition of 1.44 M sulfuric acid (17.8 mL, 26 mmol) around the probe with stirring, whereupon sodium isethionate (7.438 g, 50 mmol) dissolved in a minimal amount of 2:1 alcohol-water (about 40 mL) was added. The resulting slurry was stirred for about 2 h, whereupon it was suction filtered, and the filtrate was concentrated as far as feasible by rotary evaporation. The residue was taken up in methanol (25 mL) and loaded onto an about 20-g column of 230-400 mesh silica gel previously packed in methanol.As in Example 3, the methanolic solution of crude [TMA][ise] was pushed down to the level of the top of the silica gel bed with air pressure while the column issue was collected in a 250-mL round bottom flask; the flask previously containing the crude product was rinsed with methanol (25 mL) and the rinse methanol was similarly loaded and pressed down while the column issue was collected on top of the first fraction. The rinsing process was repeated once before the silica gel column was washed down with fresh methanol (100 mL), all the while collecting the column issue on top of the accumulated methanol solution. The combined methanolic fractions were concentrated by rotary evaporation to produce purified [TMA][ise] (10.098 g, 51 mmol, 102%) as an ionic liquid. The ionic liquid of Example 5 was solid at ambient conditions, liquid when contained in a sample vial immersed in an 80 C. water bath, and liquid in a relative humidity (RH) chamber maintained above ambient humidity but below 40% RH.
