Problems solved by technology

[0003] The vanadium removal reagents used for the removal of vanadium from organic matter mainly include fatty acid and mineral oil. Compared with mineral oil for vanadium removal, fatty acid vanadium removal has the advantages of fast speed and high efficiency. At the same time, there is also a viscous vanadium removal tailing that is not conducive to subsequent applications. Handling and other issues

Abstract

The invention discloses mixed fatty acid for removing vanadium from high-vanadium-content crude titanium tetrachloride. The molar ratio of carbon-carbon double bonds to alpha-H to carboxyl in the mixed fatty acid is as follows: the carbon-carbon double bonds: (alpha-H and carboxyl) = 0.6-0.75. According to the mixed fatty acid vanadium removal dosage, fatty acid, contained carbon-carbon double bonds, alpha-H and carboxyl main reaction groups are adopted for calculation, accurate control over the mixed fatty acid dosage can be achieved, the viscosity of vanadium removal tailings is considered at the same time, and therefore the efficient vanadium removal effect and tailing viscosity disadvantage equalization are achieved.

Description

technical field [0001] The invention relates to the field of titanium tetrachloride production, in particular to a mixed fatty acid for removing vanadium from crude titanium tetrachloride with high vanadium content and a method for removing vanadium. Background technique [0002] Titanium tetrachloride is an important intermediate product for the production of titanium metal and its compounds, and an important raw material for the production of titanium industry. In industry, titanium-rich materials such as rutile or high-titanium slag are used as raw materials to react with chlorine gas to produce titanium tetrachloride. However, the production process of titanium tetrachloride is accompanied by the formation of vanadium oxytrichloride, so that the above crude titanium tetrachloride cannot be directly used to produce sponge titanium and titanium dioxide, so it must be removed by vanadium removal process. Because the boiling points of vanadyl trichloride and titanium tetrac...
