摘　　要：利用红外光谱法对四氯化钛(TiCl_(4))中的氧碳杂质含量进行检测,并成功将该检测方法应用于精TiCl_(4)的在线检测中。在线检测系统样品池由2个腔体串联组成,光程分别是10 mm和40 mm,其中10 mm光程用于检测CCl_(4)含量,40 mm光程用于检测COS、COCl_(2)、CS_(2)、C_(6)Cl_(6)、Si_(2)OCl_(6)、TiOCl_(2)、SO_(2)Cl_(2)、SOCl_(2)、VOCl_(3)、CCl_(3)COCl等化合物含量。样品池采用纯钛材质,窗片采用ZnSn材质,均具有较强的耐腐蚀性。实践证明,该在线检测技术有效解决了精TiCl_(4)检测过程中接触空气水解的难题,使精TiCl_(4)中氧碳杂质检测更加准确。The content of oxygen and carbon impurities in titanium tetrachloride(TiCl_(4))was detected by infrared spectroscopy,and this method was successfully applied to the on-line detection of refined TiCl_(4).The sample cell of the on-line detection system consisted of two cavities in series,and the light path were 10 mm and 40 mm respectively.10 mm light path was used to detect the content of CCl_(4).40 mm light path was used to detect the content of COS,COCl_(2),CS_(2),C_(6)Cl_(6),Si_(2)OCl_(6),TiOCl_(2),SO_(2)Cl_(2),SOCl_(2),VOCl_(3),CCl_(3)COCl.The sample cell was made of pure titanium,and the window piece was made of ZnSn,which both had strong corrosion resistance.The practice shows that the on-line detection technology can effectively solve the problem of hydrolysis in air during the detection process of refined TiCl_(4),and make the detection of oxygen and carbon impurities in refined TiCl_(4) more accurate.
