摘要
碘是植物和人体生长中的重要元素之一,也是制备无机和有机碘化物的重要原料。主要从不同原料出发,简单分析了碘回收利用常见的几种方法,并结合现代工业生产技术,探讨了湿法磷酸中碘的回收利用方式,最后对碘在合成碘代苯胺、碘代苯甲酸类等医药中间体制备中的运用进行了总结。
Iodine is one of the important elements in the growth of plants and humans.It is also an important raw material for the preparation of inorganic and organic iodides.This article mainly starts from different raw materials, and briefly analyzes several methods commonly used for iodine recovery and recycling.Combined with modern industrial production technology, the recovery and utilization of iodine in wet process phosphoric acid are discussed.Finally, iodine is used in the synthesis of iodoaniline and iodobenzene.The use of formic acid and other pharmaceutical intermediates was ,summarized.
