Method for producing titanium dioxide |
| abstract |
Pigmentary titanium dioxide is produced by vapor phase oxidation of titanium tetrachloride with oxygen at elevated temperatures in a reactor. Gaseous and solid products produced by the reaction are separated and chlorine recovered from the gaseous portion in a chlorine recovery zone. Operation of the chlorine recovery zone is improved by utilizing reactant oxygen having not more than about 100 parts per million nitrogen. |
