精四氯化钛中痕量有机杂质的红外光谱分析
Determination of Trace Organic Impurities in Refined TiCl4 by Infrared Spectroscopy
摘要
Abstract
The organic impurities in TiCl4, including CC13CQC1, CHC12COC1, CH2C1COC1, CS2 and CC14, could be simultaneously determined by infrared spectral analysis due to the obvious differences of their infrared spectral characteristics. However, the traditional infrared liquid cell is not fit for the analysis of TiCl4 sample, because TiCl4 is easily hydrolyzed and could immediately reacts with moisture in the air to form highly corrosive hydrochloric acid smoke. In this paper, a new infrared measuring device with a window film of ZnSe( 025 mm x2 mm, 7 800 -440 cm" ) and a cell of PT-FE(optical path; 10 mm) was assembled and used in determination of the five organic impurities by the standard addition method. The detection limits of CC13COC1, CHC12COC1, CH2C1COC1, CS2 and CCl4 were 3. 159 ×10 -3, 1. 917 ×10-3, 1. 554 × 10 -2 , 5. 707 × 10 -3, 3. 769 × 10-1 mg· g-1 , respectively. The new infrared measuring device was safe, simple, easily removable, washable and reuseable, and the new method has a good application prospect in the real sample analysis and quality control of refined TiCl4 in titanium sponge.关键词
