Peracetic add

Diphenic acid. Phenanthrene upon oxidation in acetic acid solution at 85° with 30 per cent, hydrogen peroxide gives diphenic acid (diphenyl-2 2 -di-carboxyHc acid) no phenanthraquinone is formed under these experimental conditions. The reaction is essentially an oxidation of phenanthrene with peracetic add. (For another method of preparation, see Section I V,74.)... 

Laundry powders in Europe use sodium percarbonate and a bleach activator, tetraacetylethylenediamine ( ED), to form peracetic acid in the washing machine that then reacts with bleachable stains such as tea, red wine, coffee, and curry to remove /bleach them from cloth. Transition metal ions, in particular copper, cause first decomposition of peracetic add before it can bleach stains and second react with peroxide to form highly readive hydroxyl radicals that can cause dye and fabric damage [32]. Chelants bind with copper and other metals to prevent these unwanted side readions. 

The ionic nature of this polymerization was suggested by many other experimental evidences. For example, several other acids can replace peracetic add, but acetylperoxide cannot 16). 

Selenophene is reported to be little affected by oxidizing agents under mild conditions (B-79MI31600) and tellurophene is reported to be fairly stable to light and air at room temperature <77AHC(2l)ii9). Dibenzoselenophene forms a 5-oxide when treated with peracetic add in acetic acid, a compound also obtained when the 5,5-dibromide is reacted with dilute aqueous sodium hydroxide (50JA5753). 

Stereochemical specificity fe manifest in the reaction of frans-2,3-epoxybutane with acetic acid, which Wjiustein and Lucas reported to give only ryJAre-2-acetoxy-3-butanol (Eq. 746). Hydrolysis leads to optically inactiveme o-2,3-hutanediol. Similarly, Bdeeeken and Cohen1 had described previously the preparation of racemic [Pg.460]

Certain uneaturated fatty acids give lactone esters on treatment with peracetic acid, presumably by intramolecular attack of the carboxyl function on the initially-formed epoxide ring. Thus, 4,8-cpnxypentanoic acid generated by peracetic add oxidation of 4 pentenoie acid undergoes cleavage to give a five-membered lactone as... 

Several peroxy adds are used in the oonversion of olefins into epoxides. Their properties and pr tarations have been described by Swern, -Included among them are perfbrmio add, peracetic add, perbenxoio acid, monoperphthalic add, and percamphorio acid. More recently irifluoroperacetic acid hsa attained some prominence. Certain desirable features have been discovered in p-nitroperbenzoic add aa well. ...

Peradds are the normal reagents for effecting the conversions of dihydrothiazines and their oxides into dihydrothiazine dioxides. Thus the compound 82 was transformed into the sulfone 248 by peracetic add and the sulfoxide 219 afforded the derivative 249 when treated with m-chloroperbenzoic add. Unpublished studies, performed in the author s laboratory, have shown that compounds of type 199 are readily converted into the sulfones 250 by m-chloroperbenzoic add. In one instance, oxygen has been reported to act...

Peracetic acid is the oxidant of choice other percarboxylic acids as performic acid or m-CPBA proved to be less suitable, because they cause mainly epoxidation and consecutive reactions. Peracetic acid was used in the form of the so called peracetic acid in equilibrium or in the form of the distilled aqueous peracetic acid. Peracetic acid in equilibrium is made from acetic acid and H202 in the presence of H2S04 distilled aqueous peracetic acid is produced from it by distillation as an azeotropic mixture of peracetic add/water. 

Table 5 shows the composition of both peracetic acid types. In contrast to peracetic acid in equilibrium , which is indefinitely stable at 5 °C and may therefore be stored, distilled peracetic add decomposes. For industrial purposes it is produced on site immediately before use. However, for reasons of safety, peracetic acid should not be distilled in the laboratory ...
