Dialkylimidazolium Chloroaluminate Molten Salts,
Abstract
Earlier work has shown that mixtures of l-alkylpyridinium chlorides and aluminum chloride form electrolytes that are molten at room temperature. Molecular orbital calculations predicted that 1,3-dialkylimdazolium cations would be more stable cathodically than l-alkylpyridinium cations. A series of l-methyl-3-alkylimidazolium chlorides was synthesized and chloroaluminate melts were prepared from them. The imidazolium chlorides themselves have reduction potentials considerably cathodic of the corresponding pyridinium chlorides in DMF. The new melts have favorable physical properties and wider electrochemical windows than the earlier melts. The Lewis acidity of the melts may be varied over a very broad range.
