  • US3711592A Method for separation of tungsten chloride

    Tungsten hexachloride is separated from a mixture of metal chlorides comprising tungsten pentachloride and other metal chlorides by first distilling the mixture so as to remove lower boiling chlorides than tungsten pentachloride. The mixture is then chlorinated, preferably at a temperature around that of the boiling point of the tungsten pentachloride.
