    摘要: A process for the preparation of violet TiCl.sub.3 by reducing TiCl.sub.4 with an organo-aluminum compound, characterized in that:(a) the TiCl.sub.4 is premixed with a complexing agent in an inert organic solvent, the molar ratio complexing agent:TiCl.sub.4 being within the range from 0.3:1 to 2:1;(b) the organo-aluminum compound is premixed with a complexing agent in an inert organic solvent, the molar ratio complexing agent:organo-aluminum compound being at least 0.25:1;(c) the reduction to TiCl.sub.3 and precipitation of TiCl.sub.3 are carried out by combining at least one stoichiometric equivalent of TiCl.sub.4 in the premixed composition of step (a) with one stoichiometric equivalent of the organoaluminum compound in the premixed composition of step (b) over a period of less than one hour at a temperature within the range 60.degree. to 110.degree. C.; and(d) the final concentration of violet TiCl.sub.3 in the reaction mixture is at least 0.2 mol./liter.
