TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The sulfonate ion is isethionate, taurinate (both preferred), 3-morpholinopropane sulfonate, 4-(2-hydroxyethyl)-1-piperazine propane sulfonate (HEPPS, EPPS), 1,4-piperazine diethane sulfonate, N-(2-acetamido)-2-aminoethane sulfonate, N-cyclohexyl-3-aminopropane sulfonate, 4-(2-hydroxyethyl)-1-piperazine ethane sulfonate, 2-(2-hydroxy-1,1-bis(hydroxymethyl)ethyl)amino-ethane sulfonate, N-tris(hydroxymethyl)methyl-3-aminopropane sulfonate and/or 3-(N-tris-hydroxymethyl-methylamino)-2-hydroxypropane sulfonate. The cation is tetramethylammonium, 1-ethyl-2,3-dimethylimidazolium, 1-methyl-1,4-diazabicyclo(2.2.2)octanium (all preferred), alkyl-1,4-diazabicyclo(2.2.2)octanium (alkyl-1,4-diazabicyclo(2.2.2)octane), N-ethyl-N-methylmorpholinium and/or 1-methylimidazo(1,2-a)pyridinium. EXAMPLE - 1-Methyl-1,4-diazabicyclo(2.2.2)octanium (C1ted) isethionate (ise) was an ionic liquid comprised of (C1ted) as the cation, and (ise) as the anion. A 1-neck bottom flask holding an aqueous solution ((138.662 g)) of (C1ted) (hydroxyl) (47 ml) was fitted with a pH probe such that the probe extended below the level of the batch. The pH was adjusted to 13.71-4.96 by the addition of 1.8 M sulfuric acid (10 ml) around the probe with stirring. The mixture was concentrated as feasible by rotary evaporation to leave 8.632 g of residue, nominally considered as (C1ted)2(sulfate) (6.853 g) and water (1.779 g). Reagent alcohol (4 ml) was added to this mixture, rendering it a solution of nominal (C1ted)2(sulfate) in 2:1 alcohol-water, where sodium isethionate (5.869 g) dissolved in a minimal amount of 2:1 alcohol-water (30 ml) was added. The resulting slurry was stirred for 2 hours, where 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 20 g column of 230-400 mesh silica gel previously packed in methanol to obtain (C1ted)(ise) (87%).
