Recovery of 1-methyl-3-[6-(methylthio)hexyl]imidazolium p-toluenesulfonate: After the above extraction, the aqueous layer is concentrated in vacuo. Then, KI (0.332 g, 2.0 mmol), AcOH (2 mL) and TsOH· H2O (0.379 g, 2.2 mmol) are added to the residue at room temperature. The mixture is stirred for 1 h, quenched with a saturated aqueous Na2SO3 (5 mL) and a saturated aqueous NaHCO3 (5 mL), and extracted with CHCl3 (40 mL×3). The organic layer is dried over Na2SO4 and concentrated in vacuo to give 1-methyl-3-[6-(methylthio)hexyl]imidazolium p-toluenesulfonate (0.646 g, 84%).
