• Description

  Barium 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 ;
