摘  要:开发了一种共转化碘化法合成CF_(3)I的方法,探索CF_(3)COOH的加入对合成CF_(3)I的影响,研究了反应温度、物料比等条件对反应收率的影响,同时考察了催化剂的寿命。试验结果表明,共转化碘化法的碘单程收率、催化剂寿命、反应温度均优于传统的气相催化合成技术。A method for the synthesis of CF_(3)I by co-transformation iodination was developed.The effect of the addition of CF_(3)COOH on the synthesis of CF_(3)I was explored.The effects of reaction temperature and feed ratio on the reaction yield were studied.The life of the catalyst was also investigated.The experimental results show that the one-way iodine yield,catalyst life and reaction temperature of the co-conversion iodination method are better than those of the traditional gas phase catalytic synthesis technology.
