摘　　要：铝粉净化处理粗四氯化钛中的三氯氧钒,实质是TiCl_(3)除钒,即在AlCl;做催化剂的条件下,三氯化铝催化四氯化钛和铝粉的还原反应,直到生成除钒所需要的TiCl_(3)浆料。在制备浆料的过程中,TiCl_(3)的不同晶体结构的络合形式对粗四氯化钛的除钒能力和精制效果具有非常大的影响,通过对不同络合形式的TiCl_(3)浆料分析和工业生产试验,得出具有高活性品质的TiCl_(3)除钒浆料,其生产出的精四氯化钛指标达到99.99%以上。Aluminum powder purification of vanadium trichloride in crude titanium tetrachloride,the essence is TiCl_(3)vanadium removal,that is,under the condition of AlCl;as a catalyst,aluminum chloride catalyzed the reduction reaction of titanium tetrachloride and aluminum powder,until the formation of TiCl_(3)pulp required for vanadium removal.In the process of preparing the slurry,the complex form of TiCl_(3)with different crystal structure has a great influence on the vanadium removal ability and refining effect of crude titanium tetrachloride.Through the analysis of the slurry of TiCl_(3)with different complex forms and the industrial production test,the high active quality of TiCl_(3)vanadium removal slurry was obtained.The index of refined titanium tetrachloride reached more than 99.99%.
