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