Chemical Properties
Manganese(VII) oxide is obtained as an oil with a green metallic lustre in reflected light by the action of concentrated sulphuric acid on very pure potassium permanganate. The compound is extremely explosive and great care must be observed in the preparation and handling of this compound. The compound dissociates at about 55°C and detonates at 95°C. In a vacuum rapid and explosive decomposition occurs above 10°C. During explosive decomposition α-Mn2O3 results, but when dissociation is slow γ-MnO2 is formed. MnO7 is hygroscopic and in moist air it decomposes to Mn02 and a mixture of ozone and oxygen. The compound is stable below -10°C in anhydrous conditions. It reacts explosively with most organic compounds and attacks carbon tetrachloride even below room temperature.
