摘要
利用滴定分析、热失重分析以及XRD方法研究了EMD和KOH溶液混合后的变化。结果表明:碱与MnO2可以相互作用并导致体系温度的升高,碱浓度的下降,EMD中形成Mn3O4以及MnO2中结合水的损失。相互作用的结果与所加KOH溶液的浓度、EMD中的水含量、二者用量的比例关系以及体系的温度有关。
The changes were studied after mixing EMD with potassium hydroxide solution by the methods of titration analysis, weight lost in heat and XRD techniques. The results showed that the reaction could happen between MnO2 and KOH, could cause to raise the temperature of mixture to drop the concentration of KOH solution to form Mn3O4 in EMD and to lose the combination water content in MnO2. The interaction results had something to do with concentration of potassium hydroxide, water content in EMD, and ratio relation of amount between EMD and potassium hydroxide solution.
