摘要
介绍了从亚磷酸二甲酯的副产尾气中回收氯化氢制浓盐酸的工艺 ,采用溶剂分段循环和降温相结合的方法 ,可使氯化氢的回收率达 99%以上 ,盐酸浓度大于 30 %。
The process of recovering hydrogen chloride from the tail gas of dimethyl phosphite for producing hydrochloric acid is introduced in this paper.The rate of recovery for hydrogen chloride is over 99% by using the method of combining recycle solvent and lower temperature.The concentration of hydrochloric acid is over 30%.
