Abstract
An improved process for the preparation of TiCl.sub.4 comprising (a) chlorinating a raw material containing titanium and vanadium impurities to produce a crude TiCl.sub.4 reaction product, (b) separating the crude reaction product into solid by-products and TiCl.sub.4 -containing liquid, (c) reacting the TiCl.sub.4 -containing liquid with a reducing agent whereby vanadium impurities are converted into solid compounds, and (d) separating TiCl.sub.4 from the solid vanadium compounds, is improved by adding solid products of the vanadium reduction reactions to the crude TiCl.sub.4 reaction product prior to the separating step (b).

An improved process for the preparation of TiCl.sub.4 comprising
- (a) chlorinating a raw material containing titanium and vanadium impurities to produce a crude TiCl.sub.4 reaction product,
- (b) separating the crude reaction product into solid by-products and TiCl.sub.4 -containing liquid,
- (c) reacting the TiCl.sub.4 -containing liquid with a reducing agent whereby vanadium impurities are converted into solid compounds,
- (d) separating pure TiCl.sub.4 from the solid vanadium containing reaction products, and
- (e) separating the solid by-products and reaction products from TiCl.sub.4 is improved by adding solid products of the vanadium reduction reactions according to step (c) to the crude TiCl.sub.4 reaction product prior to the separating step (b).
