Manganese(II) acetate
Encyclopedia
Manganese acetate is the chemical compound
with the formula Mn(CH3COO)2. It is used as a desiccant
, a catalyst, and as fertilizer
.
with either manganese(II,III) oxide
or manganese(II) carbonate
:
If manganese(II,III) oxide
is used, manganese(III) oxide
is produced as a byproduct.
If the anhydrous form needs to be produced, manganese(II) nitrate
can be reacted with acetic anhydride
