Abstract
A process for the removal of aluminum chloride from a liquid solution thereof with the liquid metal chlorides resulting from the chlorination of titaniferous materials by mixing water and sodium chloride with the liquid solution in amounts such that the amount of water is less than equimolar with respect to the total amount of aluminum chloride and the combined amount of water and sodium chloride is at least equimolar with respect to the total amount of aluminum chloride. This process significantly decreases the corrosion of apparatus associated with the presence of aluminum chloride and substantially eliminates losses of titanium tetrachloride and ferric chloride present in the liquid solution and reduces the formation of HCl.
