A novel chemical redox route was developed for the preparation of water-miscible imidazolium ionic liquids (ILs). In this method, the reaction between 1-alkyl-3-methylimidazolium bromides or 3-butyl-1-phenylimidazolium bromide and the appropriate acid reactant was promoted by the redox reaction between the bromide ion and aqueous hydrogen peroxide, with hex-1-ene as both solvent and bromine scavenger. The residual bromide ion and water contents of the prepared ILs were determined by ion chromatography and the Karl-Fischer test, respectively. This method not only produces water-miscible ILs in high purity and high yield, but also simplifies the reaction conditions in comparison with previous routes.
