由软锰矿制备高锰酸钾实验技术的改进

Experimental technique improvement of potassium permanganate prepared from MnO_2

介绍了一种高锰酸钾合成实验的改进方法.通过引入一定量的醋酸为锰酸钾歧化反应的介质,得到了纯度较高的高锰酸钾产品.利用醋酸为反应介质所合成的高锰酸钾纯度(94.5%)远远高于在锰酸钾溶液中通入CO2使其歧化所得高锰酸钾的纯度(70%左右).

An experimental technique improvement method of potassium permanganate prepared from MnO2 was introduced. A high purity potassium permanganate was synthesized using acetic acide as the medium of disproportionation reaction of potassium manganate. The purity of potassium permanganate （ 94.5% ） prepared using acetic acide as the reaction medium was higher than that （ about 70% ） of sample synthesized introducing CO2 into the solution of potassium manganate.
