Electrochemical Studies of Sodium Chloride as a Lewis Buffer for Room Temperature Chloroaluminate Molten Salts

The reaction of equal molar quantities of 1-methyl-3-ethylimidazolium chloride (MEICl) with AlCl 3 results in the formation of a conductive ambient-temperature ionic liquid that, when investigated voltammetrically, exhibits 4.4V of electroinactivity between the reduction of MEI + and the oxidation of AlCl 4 − . In this paper we investigate those equilibrium processes that control the chloroacidity in these ionic liquids
