Abstract
Crude titanium tetrachloride is purified and decolorized by adding thereto from 0.01 to 0.1 per cent by weight of water, dissolving the precipitate of basic chloride so formed by stirring and adding dry and finely powdered charcoal, heating the resulting mixture to boiling point for the time necessary for the complete adsorption of the impurities by the charcoal and distilling the titanium tetrachloride. The quantity of charcoal employed is preferably 1 to 5 per cent. According to examples (1) titanium tetrachloride containing chromyl and vanadium chloride impurities was treated with a small amount of water and the basic titanium chloride formed was dissolved by stirring. Charcoal which had been dried at 100 DEG C. for five hours, was then added to the tetrachloride which was heated to boiling and kept at this temperature for five hours under reflux after which it was distilled to obtain a clear titanium tetrachloride. (2) A titanium tetrachloride containing as impurities V - Al - Fe - Mg - Ca - Zr and smaller amounts of Si - B - Sn - Ni - Mn and Na, obtained by the chlorination of rutile with coal was treated with water and after the addition of dry charcoal was brought to boiling and then immediately distilled to produce colourless titanium tetrachloride.
