General procedure: Synthesis of [CmOHMIM][HOCnSO3]) and [CmOHTEA][HOCnSO3]: ILs were prepared by ion exchange method. The ion exchange of the anion chloride by the anion hydroxyalkanesulphonate was carried out using an exchange column packed with 100 g of Amberlite IR120 H-type strongly acidic cation exchange resin. The column was previously flushed thoroughly with a 1 mol L- 1 [CmOHMIM]Cl or [CmOHTEA]Cl solution until the elution was neutral, then with Milli-Q water until no chloride was detected by silver nitrate. A 100 mL of 1 mol L- 1 Na[HOCnSO3] solution was slowly run over and eluted with Milli-Q water. The eluted liquid was collected and concentrated under reduced pressure in a rotary evaporator. The residue was then vacuum dried at 323 K for 18 h to afford the IL in near-quantitative yield as a colorless viscous liquid. ILs with ions containing hydroxyl groups are usually observed to be rather viscous. 1-(2-Hydroxyethyl)-3-methyl-imidazolium hydroxymethane sulfonate ([C2OHMIM][HOC1SO3]) 1H NMR (400 MHz, D2O, 298 K): 3.89 (s, 3H), 3.91 (t, J = 5.0 Hz, 2H), 4.30 (t, J = 4.83 Hz, 2H), 4.35 (s, 2H), 7.44 (s, 1H), 7.50 (s, 1H), 8.72 (s, 1H); 13C NMR (400 MHz, D2O, 298 K): 35.29, 51.08, 59.35, 73.71, 122.01, 123.18, 135.92.
