METHOD OF PREPARING ALUMINIUM CHLORIDE

摘要

An improved method is disclosed for producing aluminum chloride by contacting chlorine with aluminum oxide and a reducing agent, each of which is present in an amount in excess of the stoichiometric amount of the chlorine in a molten bath of aluminum chloride and metal halide to form aluminum chloride which is recovered from the bath by sublimation. The improvement comprises increasing the rate of formation of aluminum chloride by adding a source of metal selected from the group consisting of iron, chromium, copper, europium and cerium to the molten bath.
