Description

General description

Potassium permanganate (KMnO₄) exhibits strong oxidizing properties. KMnO₄ on dissolution in benzene and on complexation with dicyclohexyl-18-crown-6, affords a useful oxidizing reagent. This reagent participates as an oxidant for the oxidation of olefins, alcohols, aldehydes and alkyl benzenes under mild conditions.

Application

Potassium permanganate may be employed as an oxidizing agent in the synthesis of the following:

• sulfonal (2,2-bisethylsulfonyyl)propane
• cinchomeronic acid (pyridine-3,4-dicarboxylic acid)
• isonicotinic acid (pyridine-4-carboxylic acid)
• manganese(IV) sulfate

Suitable for heterogeneous oxidations.

Used for the decomposition of organic samples for the det. of mercury
