Manganese(VII) oxide (manganese heptoxide) is an inorganic compound with the formula Mn 2 O 7 Manganese heptoxide is a volatile liquid with an oily consistency. It is a highly reactive and powerful oxidizer that reacts explosively with nearly any organic compound .
Cadmium permanganate can also be produced by reacting manganese heptoxide with cadmium oxide [2] or cadmium hydroxide. [3] Properties.
Permanganic acid has also been prepared through the reaction of hydrofluorosilicic acid with potassium permanganate, [4] through electrolysis, and through hydrolysis of manganese heptoxide, though the last route often results in explosions. [5] Crystalline permanganic acid has been prepared at low temperatures as the dihydrate, HMnO 4 ·2H 2 O. [3]
