摘要
基于一种新颖高效气体发生装置,设计了以氯气为氧化剂,理论产率接近100%的将锰酸钾高效转化为高锰酸钾的实验方案。实验结果表明:使用本设计制备高纯度高锰酸钾,既可保证高锰酸钾的理论转化率,减少歧化反应副产物对纯度的影响,同时得到的副产品次氯酸钠及氯水可用做无机教学实验的基础试剂,符合"循环经济"指导思想。
In this paper,based on a novel and high-efficiency gas generator,an experimental scheme was designed to convert potassium manganate into potassium permanganate in a 100%theoretical yield using chlorine as oxidant.The experimental results show that a high purity potassium permanganate can be obtained using this scheme.It can not only guarantee the theoretical conversion rate of potassium permanganate,but also reduce the influence of the by-products on the purity of product using disproportionation reaction.At the same time,the by-products,sodium hypochlorite and chlorine water,can be used as basic reagents in inorganic teaching experiments well followed the guidance of"circular economy".
