一种碘化氢的生产方法

Production method of hydrogen iodide

Abstract

The invention discloses a production method of hydrogen iodide, which adopts a red phosphorus method and comprises a reacting step, a filtering step and a distilling step sequentially. In the reacting step, deionized water is added into reaction equipment; after red phosphorus and iodine are added, the weight ratio of the reaction material liquid is measured and is controlled to be between 1.2 and 1.4; and hydroiodic acid steam is absorbed by a water spraying pump. The filtering step includes two times of filtering. The production method provided by the invention solves the problem of difficult realization of mass production, and avoids the occurance of explosion, has high production efficiency and contributes to environmental protection at the same time.
本发明公开了一种碘化氢的生产方法,采用红磷法,依次包括反应步骤、过滤步骤和蒸馏步骤,在反应步骤中,向反应设备内加入去离子水,加完红磷和碘后,测定反应料液的比重,控制其比重在1.2~1.4,氢碘酸蒸汽用水喷泵吸收,过滤步骤为两次过滤,本发明提供的生产方法,解决了大规模生产不易实现的问题,控制了爆炸的发生,生产效率高,同时利于环保。
