Peroxymonosulfuric acid oxidant

The displacement of alkoxy groups from polynitroarylenes has been used for the indirect synthesis of some highly nitrated polynitroarylenes. Holleman synthesized 2,3,4,6-tetranitrotoluene (57) by treating 3-methoxy-2,4,6-trinitrotoluene (132) with ammonia in methanol, followed by oxidation of the resulting product (56) with peroxymonosulfuric acid. 

Peroxymonosulfuric acid (Caro s acid, H2S05) and its salts may be used to oxidize aldehydes. Although early results were poor compared with the use of organic peracids, good yields of esters have been obtained when reactions are carried out in the presence of alcohols.225 Unsaturated and aromatic aldehydes undergo analogous reactions. It is believed that hemiacetal formation occurs in these reactions, and that it is this species which is oxidized, rather than the aldehyde. 

Combustible when exposed to heat, flame, or oxidizers. Potentially explosive reaction with aluminum chloride + nitromethane (at 110°C/100 bar), formaldehyde, peroxydisulfuric acid, peroxymonosulfuric acid, sodium nitrite + heat. Violent reaction with aluminum chloride + nitrobenzene (at... 

Finally, a number of commonly occurring atmospheric trace species are converted to reactive electrophiles in concentrated sulfuric acid solutions. For example, nitric acid is converted to NO2, which is a potent nitrating agent for aromatic compounds (Liler 1971), and hydrogen peroxide can be converted to peroxymonosulfuric acid (HOOSO2OH), which is a strong oxidant (Mozurkewich 1995 Dalleska et al. 2000). 

The oxidation of aquated sulfur dioxide proceeds via a nucleophilic displacement of HSO3 by H202 to form peroxymonosulfurous acid as an intermediate that, in turn, undergoes an acid-catalyzed (both specific-acid and general-acid) rearrangement to give the products as described by the stoichiometry of Eq. 46 (McArdle and Hoffmann, 1983). The mechanism can be written as follows ... 

Peroxymonosulfuric acid (PMS) is a stronger oxidizing agent than hydrogen peroxide or peracetic acid [110] and can act as either an electrophilic or a nucleophilic reagent...

Caro s acid EINECS 231-766-6 Peroxymonosulfuric acid Peroxomonosulphuric acid. Used In dye manufacture, oxidizing agent, bleaching. Viscous liquid. 

Peroxymonosulfuric acid is used as an oxidizing agent to make glycols, lactones, and esters for making dyes and in bleaching composition. 

Hypochlorite is formed by the in situ oxidation of chloride ions by peroxymonosulfuric acid and its salts. " " Ketones such as acetone and aromatic diols catalyze the reaction. Bromides can be used in place of chlorides to form hypobromite, and such combinations are used to disinfect spas and hot tubs. 

Like peroxymonosulfuric acid, the above salt mixture is a powerful oxidant with a wide range of application unlike peroxymonosulfuric acid the mixture can be stored without appreciable loss of active oxygen and handled with negligible hazard to the user.— E Dodecyl mercaptan shaken 30 min. with an... 

Peroxyacids are the most widely used class of oxidant for aromatic amino to nitro group conversion and include peroxydisulfuric, peroxymonosulfuric, peroxyacetic, peroxytrifluo-roacetic and peroxymaleic acids. The oxidizing potential of the peroxyacid is, as a rule, proportional to the strength of the parent deoxy-acid. Dimethyldioxirane (DMDO) and ozone have also found use for amino to nitro group conversion.
