Titanium trichloride initially purified by washing with an inert aliphatic, cycloaliphatic or aromatic hydrocarbon, e.g. n-heptane, is further purified by refluxing or agitating with 1-50 mole per cent of an aliphatic amine or a heterocyclic basic nitrogen containing compound together with an aliphatic, cycloaliphatic or aromatic hydrocarbon for approximately one hour at a temperature not exceeding 100 DEG C. The preciptate is then suction filtered and washed again with an inert hydrocarbon, e.g. n-heptane. Specified aliphatic or heterocyclic basic nitrogen containing compounds or pyridene, quinoline, iso-quinoline, amylamine, trimethylamine or n-butylamine. The purified titanium trichloride is subsequently used in conjunction with an organic aluminium compound as a catalyst for a -olefine polymerization. |
