摘要
通过实验,提出了由单质碘制备碘化氢的反应机理,过程中同时存在主反应(碘化氢制取)和副反应(变换反应)两个竞争反应,三价铑羰基络合物受水亲核攻击产生的氢迅速与络合的碘作用生成碘化氢,只有在可络合的碘消耗殆尽时,副反应才进一步进行。
On the basis of experiments, a new reaction mechanism for the preparation of hydrogen iodide from iodine was proposed. There axe two competitive reactions in the process of hyrogen iodide's preparation. One is the main reaction in which the hydrogen iodide is formed. The other one is the water-gas shift reaction which produces hydrogen. The hydrogen which is produced through the water's nucleophilicly attacking to the trivalence carbonyl rhodium complex will quickly react with complex iodine to form hydrogen iodide. When the iodine is consumed, the water-gas shift reaction occurs.
