Halide anion effects of ILs were investigated using eight IL samples: [BMIm]Cl (1-butyl-3-methylimidazolium chloride; Aldrich 97%), [BMIm]Br (Aldrich, 97%), [BMIm]I (prepared), [EMIm]Cl (1-ethyl-3-methylimidazolium chloride; c-tri Korea, 98%), [HMIm]Cl (1-hexyl-3-methylimidazolium chloride; c-tri Korea, 98%), [OMIm]Cl (1-octyl-3-methylimidazolium chlo-ride; c-tri Korea, 98%), [BMpyri]Cl (1-butyl-4-methylpyridini-um chloride; prepared, 98%) and [BMpyrr]Cl (1-butyl-4-methyl-pyrrolidinium chloride; prepared, 98%).For the preparation of [BMIm]I, [BMIm]Cl (0.05 mol) was dissolved in acetonitrile. NaI (0.05 mol) was added in the [BMIm]Cl solution, which was stirred at room temperature for 48 h. Then, the solution was filtered to remove KCl, and dried with MgSO |
