Potassium permanganate was comparatively easy to manufacture, so Condy was subsequently forced to spend considerable time in litigation to stop competitors from marketing similar products.[40]. Potassium permanganate is sensitive to temperature extremes and performs best between 50 and 72 degrees Fahrenheit. On this Wikipedia the language links are at the top of the page across from the article title. Potassium permanganate (KMnO 4) is a very strong oxidant able to react with many functional groups, such as secondary alcohols, 1,2-diols, aldehydes, alkenes, oximes, sulfides and thiols.Under controlled conditions, KMnO 4 oxidizes primary alcohols to carboxylic acids very efficiently. It is on the World Health Organization's List of Essential Medicines. Essentially the first step is that KMnO4 removes a hydrogen from the benzylic position, forming a benzyl radical, and the oxygen then "rebounds" back to the carbon to form C-O. EC No. In permanganate anion (MnO4-) the manganese atom is bonded with four oxygen atoms through three double bonds and one single bond. : . Using the principles above, we expect KMno4 to react with alkenes, alkynes, alcohols, aldehydes and aromatic side chains. This behaviour is also used as a qualitative test for the presence of double or triple bonds in a molecule, since the reaction decolorizes the initially purple permanganate solution and generates a brown precipitate (MnO2). This report represents the first description of the production of potassium permanganate. He patented this solution, and marketed it as 'Condy's Fluid'.
