Oxidizing agents potassium manganate

Thus, when manganese dioxide is fused with potassium hydroxide and an oxidizing agent, the salt potassium manganate is formed. This salt is soluble in water and is fairly stable as long as a considerable excess of potassium hydroxide is present but in presence of an acid — even as weak a one as carbonic acid — the... 

Oxidation of aromatic systems containing alkyl side-chains results in the formation of a carboxylic acid, irrespective of the length of the side-chain. The usual oxidizing agents are potassium permanganate [potassium manganate(VII)] or chromic acid [chromium(VI) acid]. For example, 1,4-dimethylbenzene is oxidized to benzene-1,4-dicarboxylic acid (tereph-thalic acid, 9), an important building block for polyesters. The oxidation of isopropylbenzene (cumene) to phenol is an important industrial process and is discussed in Chapter 4. 

Potassium permanganate is obtained from manganese dioxide by oxidation in two stages. The first is carried out by fusion with alkali (potassium hydroxide) in the presence of air or another oxidizing agent and yields potassium manganate, K2Mn04. This is taken up in water and decomposed into potas-... 

Strong oxidizing agents, such as acid potassium permanganate (manganate(VII)) solution or chromic acid (acidified sodium dichromate(Vl) solution) will also oxidize alcohols. 

Potassium manganate(VII) is widely used as an oxidizing agent and as a disinfectant in a variety of applications, and as an analytical reagent. 

Potassium permanganate is widely used as an oxidizing agent, especially for oxidation in the fine organic chemicals industry. World production is about 40 000 ton yr , by far the largest plant being 15 000 ton yr sited in the USA. The electrochemical step is the oxidation of manganate...
