A process for removing one or more contaminants of the formula TiCl<sub>3</sub>OR, in which R is an alkyl or aryl group, from a liquid phase comrising TiCl<sub>4</sub>, characterized in that the contaminants are reacted with an organic acid halide R'-C" O Cl, in which R' is an aryl or alkyl group, to precipitate an addition complex of the formula nTiCl<sub>4</sub>.R'-C "O OR, in which n is a number of from 0.3 to 3.0, and the addition complex is separated from the liquid phase. |
