摘要
Process for the production of a nearly aluminum chloride-free titanium tetrachloride from titaniferous raw materials containing larger quantities of aluminum compounds in a fluid bed with the addition of a reducing agent. In the process, sodium chloride is added to or formed in the reaction mixture before the first condensation step. A sodium chloride/aluminum chloride complex is formed thereby, which is discharged together with the chloride mixture and separated from said mixture together with the metal chlorides of lower volatility. The maximum quantity of NaCl needed is 1 mole per mole Al contained in the titaniferous raw material and per mole of iron (III) chloride, calculated as FeCl3, that may form.
