Abstract

Aluminum bromide is prepared by an electrochemical process in a cell with an aluminum anode, employing as the electrolyte, a solution of hydrogen bromide in an aprotic solvent capable of dissolving both hydrogen bromide and aluminum bromide. After initiation of the reaction with an electric current, the reaction proceeds without additional electrical power. The product is a solution of aluminum bromide and may also include solid aluminum bromide if the amount produced exceeds the solubility limit of the solvent.
