摘要： In the purification of impure titanium tetrachloride comprising adding an agent to said titanium tetrachloride and thereafter distilling off purified titanium tetrachloride while leaving the impurity in the distillation residue, the improvement which comprises employing as said agent at least one amine of the formula ##EQU1## in which R.sub.1 and R.sub.2 each independently is hydrogen, alkyl or alkenyl of up to 6 carbon atoms, cycloalkyl of 5 to 7 carbon atoms, or aryl, andR.sub.3 is cycloalkyl of 5 to 7 ring carbon atoms, or aryl, orR.sub.2 together with R.sub.3 is butylene, pentylene or hexylene, in which eventR.sub.1 is hydrogen, alkyl of up to 6 carbon atoms or aryl.The preferred agents are aniline, cyclohexylamine, N,N-dimethyl-aniline, diphenylamine, 2,3-dimethyl-aniline and 2,6-dimethyl-aniline. The process serves to remove vanadium impurities.

摘要： 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).
