Manganese nitrate tetrahydtate - Production method
The pyrolusite method mixes pyrolusite and pulverized coal in a certain proportion and is roasted. The generated manganese monoxide reacts with nitric acid to generate manganese nitrate. After filtration and concentration, a manganese nitrate solution is prepared. br />
MnO2 C→MnO CO↑
Mn02 CO→Mn0 CO2↑
MnO 2HNO3→Mn(NO3)2 H2O
The metal manganese method adds metal manganese to a dilute nitric acid solution for reaction to generate manganese nitrate. The solution is purified and filtered to obtain a manganese nitrate solution. Its
3Mn 8HNO3→3Mn(NO3)2 2NO 4H2O
