Abstract

An improved process for the preparation of TiCl.sub.4 comprising PA0 (a) chlorinating a raw material containing titanium and vanadium impurities to produce a crude TiCl.sub.4 reaction product, PA0 (b) separating the crude reaction product into solid by-products and TiCl.sub.4 -containing liquid, PA0 (c) reacting the TiCl.sub.4 -containing liquid with a reducing agent whereby vanadium impurities are converted into solid compounds, and PA0 (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).
