Description
orange-brown to brown powderManganese (III) acetate is an inorganic compound that is used as an oxidizing agent in organic synthesis and materials science. Like the analogous acetates of iron and chromium, it is an oxygen-centered coordination complex containing three manganese atoms bridged by acetate units. The anhydrous form of this compound crystallizes as a linear coordination polymer, with an additional acetic acid molecule bridging between manganese atoms on consecutive three-manganese c
Manganese triacetate dihydrate Use and Manufacturing
To a 2 L round-bottomed flask, Mn(OAc)2•4H2O (66 g, 0.27 mol) and glacial AcOH (660 mL) were added and the mixture was heated at 90°C to dissolve the components (normally for 10-30 min). The mixture must not be heated under reflux. After cooling, acetic anhydride (96 mL) was added to the mixture with stirring. Three portions of ground potassium permanganate, KMnO4, (11 g, 0.07 mol) were then slowly added with stirring. The mixture was heated under reflux for 1 h (Caution: the added KMnO4 must be dissolved in the reaction mixture. Otherwise the reaction mixture could be bumpy while cooling on the bench Very dangerous). After cooling, water (110 mL) was added and the mixture was kept at room temperature under dark conditions until the dark color of the supernatant solution turned transparent normally within for 2 weeks. The crystalline manganese(III) acetate formed was filtered, washed three times with glacial AcOH, washed twice with dried Et2O, and dried in a desiccator under reduced pressure using KOH as a drying agent, resulting in the bright-brown color of Mn(OAc)3•2H2O (67 g, 93percent yield).
Oxidation catalyst, preparation of brown dye, paint drier, etc.
