Abstract
本发明涉及无机化工领域,具体涉及一种制备硫酸氢钠的方法;以硫代硫酸钠或亚硫酸氢钠为原料,以过氧化氢为氧化剂,通过氧化还原反应,制备硫酸氢钠;本发明方法采用的原料为硫代硫酸钠或亚硫酸氢钠是常见的无机盐,无腐蚀性,而过氧化氢是一种对环境友好的清洁氧化剂,避免了以强酸、强碱为原料对设备产生的腐蚀,采用本发明制备方法安全性高,且方法操作过程简单,因此可望成为硫酸氢钠的一种清洁制备方法。The invention relates to the field of inorganic chemical industry, in particular to a method for preparing sodium bisulfate; using sodium thiosulfate or sodium bisulfite as a raw material, using hydrogen peroxide as an oxidant, and preparing sodium bisulfate through a redox reaction; the present invention The raw materials used in the method are sodium thiosulfate or sodium bisulfite, which are common inorganic salts and are non-corrosive, while hydrogen peroxide is an environmentally friendly cleaning oxidant, which avoids the generation of equipment by using strong acids and alkalis as raw materials. The preparation method of the present invention has high safety and simple operation process, so it is expected to be a clean preparation method of sodium hydrogen sulfate.
