Abstract
An improved process is provided for producing titanium tetrachloride vapor admixed with a desired particular amount of aluminum trichloride vapor for use in the production of rutile titanium dioxide. The vapor mixture is derived from a titanium tetrachloride solution containing the desired particular amount of aluminum trichloride. The solution is produced continuously by dissolving aluminum trichloride in a heated stream of liquid titanium tetrachloride utilizing a cyclic aluminum trichloride bed switching and recharging process.
