Abstract
In a process for purifying aluminum chloride made by the high temperature chlorination of an aluminum value containing material by distilling the aluminum chloride in a still, and separating the aluminum chloride the improvement comprising adding sufficient alkali chloride to the aluminum chloride as to provide an aluminum chloride/alkali chloride mixture having a conductivity sufficient to permit internal electrical resistance heating of the still when an electric current is applied across the still mixture.
