DescriptionBarium manganate (chemical formula BaMnO4) is a type of manganates in which the manganese is in a +6 oxidation state. It is obtained by heating manganese dioxide with barium carbonate or nitrate, or by precipitating potassium manganate with barium chloride.1 Barium manganate gives a green pigment, which was used to make manganese blue. Barium manganate can be used in the oxidation of a variety of functional groups efficiently and selectively: alcohols to carbonyls, alcohols to aldehydes, diols to lactones, thiols to disulfides, aromatic amines to azo-compounds, hydroquinone to p-benzoquinone, benzylamine to benzaldehyde, etc. 2,3

UsesUseful for the selective oxidation of diols.

UsesAs pigment in fresco painting instead of Scheele's green because not so poisonous as latter. As mild oxidizing agent in organic synthesis.
