133 gms of the titanium trichloride were introduced into a stainless steel ball mill, 9 inches long and 5.1 inches diameter containing 685 stainless steel balls of diameter 0.5 inches. Hexamethylphosphoric triamide (HMPT) was added as a solid in an amount calculated to give a molecular ratio HMPT/titanium trichloride of 0.167. The contents of the mill were shaken manually to disperse the HMPT over the particles of TAC 131 and the mill was rotated for 22 hours at 45 rpm. A nitrogen atmosphere was maintained in the mill at all times.
