METHOD FOR PRODUCING MANGANESE MONOXIDE Russian patent published in 2022 - IPC C01G45/02 

FIELD: chemical compounds production.

SUBSTANCE: invention relates to the production of chemical compounds in a nanodispersed state, in particular manganese monoxide MnO, which can be used as an effective electrode material for lithium-ion and zinc-ion current sources, as well as antidiabetic and antioxidant drugs. The method includes obtaining a mixture of aqueous solutions of potassium permanganate KMnO₄ and an organic acid, followed by filtration, washing, drying and annealing in an inert atmosphere. At the same time, ascorbic acid C₆H₈O₆ is used as an organic acid at a ratio of components, mol: potassium permanganate : ascorbic acid = 1:(1.5-2.5), and annealing is carried out at a heating rate of 3-5 deg/min in a nitrogen flow at temperature 500-650°C for 1-2 hours.

EFFECT: obtaining manganese monoxide without impurities, as well as reducing the duration of the process.
