POTASSIUM PERMANGANATE SYNTHESIS METHOD Russian patent published in 2009 - IPC C01G45/12 C01D13/00 

FIELD: chemistry.

SUBSTANCE: method of producing potassium permanganate involves reacting potassium superoxide (KO₂) and manganese dioxide (MnO₂) in the presence of fuel in form of carbon, with the following ratio of components (wt %): potassium superoxide (KO₂) 46.9-52.7; manganese dioxide (MnO₂) 45.3-52.6; carbon (C) 0.5-2.0. The initial components are mixed in two steps, where manganese dioxide and fuel are mixed at the first step, and potassium superoxide is added to the obtained mixture at the second step. The process is initiated through local heating the obtained mixture at temperature of about 500°C.

EFFECT: reduced power input in synthesis of potassium permanganate and increased content of the basic substance in the synthesis product.
