Titanium dioxide (TiO2) is an oxide of titanium, and is called titanium dioxide when used as a pigment. This compound is a white solid that is insoluble in water, and its ore can be black. This compound has a wide range of uses as a pigment, and can be used as a paint, sunscreen, and food coloring.
There are two methods for producing titanium dioxide: sulfuric acid method and chlorination method. The sulfuric acid method is to hydrolyze ilmenite with concentrated sulfuric acid into a block solid phase, and then extract it with acidic water to obtain titanium liquid. After sedimentation to remove impurities and freezing to separate the by-product ferrous sulfate, seed crystals are added to decompose titanyl sulfate to produce metatitanic acid. After washing to meet the standards, it is calcined and crushed to obtain titanium dioxide.
Reaction equation:
“ 2H2SO4 + TiO2→Ti(SO4)2 + 2H2O
Ti(SO4)2 + H2O→ TiOSO4 + H2SO4
TiOSO4 + H2O→H2TiO3↓+ H2SO4 H2TiO3·SO3→TiO2+H2O+SO3↑ ”
Error to be corrected
The chlorination method is to mix the crushed rutile or high-titanium slag with coke, react with chlorine in a fluidized bed chlorination furnace to generate titanium tetrachloride, purify it, add a crystal conversion agent to oxidize it in high turbidity to generate titanium dioxide, and then wash it with water, dry it, and crush it. Reaction equation:
2TiO2 + 3C + 4Cl2→2TiCl4 + 2CO↑+ CO2↑
TiCl4 (g) + O2 (g) → TiO2 (s) + 2Cl2 (g)
