Hexachloroethane, removal from zirconium chloride

Hexachloroethane, removal from zirconium (IV) chloride, 4 124 Hexachloroplumbic(IV) acid, 1 48 Hexaguanidonium tetraphosphate 1-hydrate, 5 97, 100 Hexahalogenoplumbic acids, 1 48 Hexahalogenotellurates(IV), 2 188 Hexaiodostannates(IV), formation of, by tin(IV) iodide, 4 121 Hexametaphosphates (see Metaphosphates)... 

Two impurities are apparent in the product, iron (III) chloride and hexachloroethane. Both are more volatile than zirconium tetrachloride. Nevertheless, if both are to be removed from the product, considerable product inevitably sublimes beyond K. The amount of hexachloroethane impurity is roughly a function of temperature, since runs made at 450° yield virtually none, whereas if the furnace is allowed to go much above 500°, appreciable quantities are formed. The amount of iron (III) chloride impurity depends on the purity of starting materials. ...
