Barium peroxide Barium peroxide Barium peroxide is the inorganic compound with the formula BaO. This white solid (gray when impure) is one of the most common inorganic peroxides, and it was the first peroxide compound discovered. Being an oxidizer and giving a vivid green colour upon ignition (as do all barium compounds), it finds some use in fireworks; historically, it was also used as a precursor for hydrogen peroxide. Barium peroxide is a peroxide, containing subunits. The solid is isomorphous to calcium carbide, CaC. Barium peroxide arises by the reversible reaction of O with barium oxide. The peroxide forms around 500 °C
Barium manganate diols to lactones, thiols to disulfides, aromatic amines to azo-compounds, hydroquinone to p-benzoquinone, benzylamine to benzaldehyde, etc.. It does not oxidize saturated hydrocarbons, alkenes, unsaturated ketones, and tertiary amines. Barium manganate is a common substitute for MnO. It is easier to prepare, reacts more efficiently, and the substrate:oxidant ratios are closer to theory. Another use for barium manganate was as a pigment for making the artist’s color manganese blue. It is no longer used for that purpose; instead, paint manufacturers substitute a synthetic manganese blue hue. Barium manganate Barium manganate is an inorganic compound with the formula BaMnO. It is
