Determination of Titanium Oxychloride in Refined Titanium Tetrachloride by Infrared Spectroscopy

Abstract:

Determination of TiOCl₂ in refined TiCl₄was significant for analysis of its impurities. TiOCl₂ could be determined by infrared spectroscopy due to its infrared characteristic spectrum line. However, normal infrared absorption cell was not fit for the sample analysis, because TiCl₄ easily reacted with moisture in the air and immediately was hydrolyzed to form highly corrosive hydrochloric acid smoke. The infrared absorption cell with the window film of ZnSe ( Ф10×1mm, wavenumbers: 7800cm^-1~440cm^-1) and the glass cell (optical path: 22mm, 12mm, 7mm and 4mm) was assembled and utilized in determination of the TiOCl₂ in refined TiCl₄ by standard addition method. The detection limit of TiOCl₂ was 26.5mg•kg^-1, the regression equation was Y=1.0118X, R²=0.9926; With standard addition method, the regression equation of TiOCl₂ was Y=1.9400X, R²=0.9940,This infrared absorption device was safe, simple and convenient, easily removable and washable, and re-useable. This method could meet the requirement of determination of TiOCl₂ in refined TiCl₄.
