Description
Manganese (II) acetate is the chemical compound with the formula Mn(CH3COO)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.
Reactions
Manganese (II) acetate can be formed by reacting acetic acid with either manganese (II,III) oxide or manganese (II) carbonate :
Mn3O4 + 2CH3COOH → Mn(CH3COO)2 + Mn2O3+ H2O
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.]
