Titanium tetrachloride is produced by reacting a titaniferous material having a particle size of 150 mesh or less (Tyler standard) as a median value with a chlorine-containing gas in the presence of a coarse carbonaceous substance in a dilute-phase fluidization system.

Process for production of titanium tetrachloride

A chlorine-containing gas is introduced as an upward flow into a vertical, upwardly widening column-type reactor, and a titaniferous material and a solid carbonaceous reducing agent are charged into the reactor at its upper and lower parts to effect chlorination in a dilute-phase fluidization system accompanied by reflux of part of the solid materials and thereby yield titanium tetrachloride.
