A method for the synthesis of CF3I by co-transformation iodination was developed.The effect of the addition of CF3COOH on the synthesis of CF3I 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.
