Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.
Potassium permanganate (KMnO 4) is a dark violet colored powder. Its reaction with glycerol (commonly known as glycerin or glycerine) (C 3 H 5 (OH) 3) is highly exothermic, resulting rapidly in a flame, along with the formation of carbon dioxide and water vapour:
By removing ethylene by oxidation, the permanganate delays the ripening, increasing the fruit's shelf life up to 4 weeks without the need for refrigeration. [ 52 ] [ 53 ] [ 54 ] The chemical reaction, in which ethylene (C 2 H 4 ) is oxidised by potassium permanganate (KMnO 4 ) to carbon dioxide (CO 2 ), manganese oxide (MnO 2 ) and potassium ...
Rather, it is formed by oxidation of dimethyl sulfide with an oxidant (NCS). The reaction mechanism of Corey–Kim oxidation. Under Corey–Kim conditions allylic and benzylic alcohols have a tendency to evolve to the corresponding allyl and benzyl chlorides unless the alcohol activation is very quickly followed by addition of triethylamine. In ...
A tertiary propargylic alcohol is fragmented upon treatment with Fetizon's reagent. Halohydrins that possess a trans stereochemistry have been demonstrated to form epoxides and transposed products in the presence of Fétizon's reagent. Halohydrins possessing a cis-stereochemistry seem to perform a typical Fétizon's oxidation to a ketone. [17]
Glycol cleavage is a specific type of organic chemistry oxidation. The carbon–carbon bond in a vicinal diol (glycol) is cleaved and instead the two oxygen atoms become double-bonded to their respective carbon atoms. Depending on the substitution pattern in the diol, these carbonyls will be ketones and/or aldehydes. [1]
With many Americans focused on their glucose intake, food labels often advertise that a product is “sugar free” or has “no sugar added.” But there’s one sweet ingredient that many ...
A permanganate can oxidize an amine to a nitro compound, [7] [8] a secondary alcohol to a ketone, [9] a primary alcohol or aldehyde to a carboxylic acid, [10] [11] a terminal alkene to a carboxylic acid, [12] oxalic acid to carbon dioxide, [13] and an alkene to a diol. [14] This list is not exhaustive. In alkene oxidations one intermediate is a ...
