摘　　要：分析了粗四氯化钛除杂现有工艺的不足,介绍了一种利用碱液实现粗四氯化钛除杂的方法。将30%~60%碱液通过喷射方式加入到粗四氯化钛中,经沉降、固体分离后,将粗四氯化钛中的固体杂质FeCl3、AlCl3、SiCl4除去。该方法能够加快四氯化钛中固体杂质的沉降速率,有效提高除杂效率,将粗四氯化钛固液比降低到0.5%以下。This paper analyzes the shortages of existing technology on TiCl_4 impurity removal, introduces a method of TiCl_4 impurity removal method using lye. The 30% ~60% lyesolution by spraying was added to TiCl_4, through sedi-mentation, solid separation, the solid impurities of FeCl_3, AlCl_3, SiCl_4 in TiCl_4 were removed. The method can speedup the settlement rate of the solid impurities in TiCl_4, effectively improve the efficiency of removing impurity, and re-duce the ratio of solid and liquid in TiCl_4 to 0.5%.
