高锰酸铵
高锰酸铵，又称过锰酸铵，是一种紫色固体，斜方晶系，分子式为NH4MnO4，可溶于水。高锰酸铵不稳定，在室温下也会缓慢分解。
高锰酸铵通常利用碳酸铵和高锰酸铝的复分解反应来制备：
- 6 KMnO4 + 4 Al2(SO4)3·18 H2O + 6 H2O → 2 Al(MnO4)3 + 6 KAl(SO4)2·12H2O
- 2 Al(MnO4)3 + 3 (NH4)2CO3 + 3 H2O → 2 Al(OH)3 + 3 CO2↑ + 6 NH4MnO4

Ammonium permanganate 高锰酸铵
Ammonium permanganate is the chemical compound NH4MnO4, or NH3·HMnO4. It is soluble in water. It is a strong oxidizer, owing to its permanganate anion, and it is a moderately strong explosive, owing to the combination of oxidizer permanganate anion and reducing ammonium cation. Dry ammonium permanganate can detonate by heat, shock, or friction, and it may explode at temperatures above 140 °F (60 °C).
