为了进一步了解四氯化钛制备中加碳氯化反应,通过计算对二氧化钛加碳氯化的CO与CO2摩尔比值、配碳比等进行了研究,发现它们对加碳氯化反应产生重要影响,低温下加碳氯化反应主要生成CO2,高温下主要生成CO。当配碳比较高时,碳的反应不完全,存在过量;较低时,不利于TiO2的完全反应。对工业TiCl4生产的CO与CO2摩尔比值进行了详细阐述。同时对低价钛氧化物的生成进行了探讨,认为不会生成低价钛氧化物。通过实验讨论了TiO2与TiCl4间的反应,发现TiO2与TiCl4间的反应能够发生,并随温度的升高而加强。研究结果为进一步优化加碳氯化反应提供了依据。
In order to know more about the carbochlorination reaction in the preparation of titanium tetrachloride, the molar ratio of carbon dioxide to carbon dioxide and the carbon to carbon ratio of titanium dioxide were calculated. It was found that they had an important influence on the addition of chlorination, The addition of carbochlorination at low temperature produces mainly CO2, which is mainly generated at high temperatures. When the ratio of carbon is high, the reaction of carbon is incomplete and there is excess; when it is low, it is unfavorable to the complete reaction of TiO2. The molar ratio of CO to CO2 in industrial TiCl4 production was elaborated. At the same time, the formation of low-cost titanium oxide was discussed, and it is considered that low-cost titanium oxide will not be formed. The reaction between TiO2 and TiCl4 was discussed experimentally, and it was found that the reaction between TiO2 and TiCl4 could occur and strengthened with the increase of temperature. The results provide the basis for further optimization of carbochlorination.
