Description
Manganese (II) acetate is the chemical compound with the formula Mn(CH
3COO)
2. It is used as a desiccant, a catalyst, and as fertilizer.
Chemical Properties
Pale-red crystals.Soluble in water and alcohol. Combustible.
Uses
Textile dyeing, oxidation catalyst, paint and
varnish (drier, boiled oil manufacture), fertilizers,
food packaging, feed additive.
Uses
Manganese(II) acetate is used as a dye mordant and varnish drier. It is also used in fertilizers, food packaging and feed additives. Further, it serves as a desiccant, catalyst, intermediate and ion exchange agent.
Reactions
Manganese (II) acetate can be formed by reacting acetic acid with either manganese (II,III) oxide or manganese (II) carbonate :
Mn
3O
4 + 2CH
3COOH → Mn(CH
3COO)
2 + Mn
2O
3+ H
2O
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.
Purification Methods
Crystallise it from water acidified with acetic acid. [Beilstein 2 IV 120.]
