Description

General description

Potassium permanganate (PP, KMnO4) is a dark violet colored crystalline solid. It is a strong oxidizing agent used in the oxidation of a wide range of organic compounds. PP is commonly used as a disinfectant to treat external infections in aquaculture. Corncobs pretreated with alkaline potassium permanganate solution showed high carbohydrate recovery due to the increased enzymatic hydrolysis of lignocellulose. The acidic potassium permanganate chemiluminescence detection has been employed for the detection of cannabinoids.

Application

Potassium permanganate was used in the preparation of layered MnO2 which may be employed as cathodic material in lithium secondary batteries.
It may be used as an oxidant in:
• The reduction of polycyclic aromatic hydrocarbons found in coal tar pitches (CTPs).
• Oxidation of decabromodiphenyl ether in sulfuric acid medium.
• Oxidative cleavage of oximes to the corresponding carbonyl compounds potassium permanganate supported on kieselguhr.
• Oxidation of progestagens.

Suitable for heterogeneous oxidations.
