Abstract

The invention relates to the field of titanium tetrachloride refining and discloses an organic reagent for removing vanadium and a method for removing vanadium from titanium tetrachloride. The organic reagent for removing vanadium comprises saturated fatty acid and unsaturated fatty acid. With the total volume of the organic reagent as the reference, the content of saturated fatty acid is larger than 0 and smaller than or equal to 60% by volume, the content of unsaturated fatty acid is larger than or equal to 40% by volume and smaller than 100% by volume, the chain length of saturated fatty acid ranges from C5 to C9, and the chain length of unsaturated fatty acid ranges from C10 to C30. The organic reagent for removing vanadium is high in vanadium removing speed, good in effect and small in quantity of generated residues.

Description

technical field [0001] The invention relates to the field of refining titanium tetrachloride, in particular to an organic reagent for removing vanadium and a method for removing vanadium from titanium tetrachloride. Background technique [0002] Titanium tetrachloride is the most important intermediate product in the production of titanium dioxide by the chloride method and the production of sponge titanium by the Krall method. Crude titanium tetrachloride is a reddish brown or dark yellow turbid liquid, and its color is related to the impurity content in it. The impurity components in crude titanium tetrachloride are very complex, among which vanadium is a main impurity element in crude titanium tetrachloride, which is represented by VOCl 3 form exists in it. VOCl 3 When it is reduced, the oxygen element may enter the sponge titanium at four times the concentration, resulting in an increase in the oxygen content in the sponge titanium, an increase in the Brinell hardness...
