Sodium peroxydisulfate

Potassium peroxymonosulfate, introduced in the late 1980s, is finding increasing use as an auxiUary oxidant for shock treatment and oxidation of chloramines. Sodium peroxydisulfate is also being sold for shock treatment, however, it is less reactive than peroxymonosulfate. Mixtures of sodium peroxydisulfate and calcium hypochlorite can be used for shock treatment (28). Disadvantages of peroxymonosulfate and peroxydisulfate are they do not provide a disinfectant residual and peroxymonosulfate oxidizes urea and chloramines to nitrate ion, which is a nutrient for algae. 

Carboxylic acids can be converted into the corresponding peroxy acids using peroxydisulfate in the presence of a phase transfer catalyst in good to excellent yields . When o-methylbenzoic acid was treated with sodium peroxydisulfate in the presence of Ag(I)/Cu(It), the corresponding lactone was obtained in 56% yield. Acyl radicals were also trapped by quinohnes or alkenes in the presence of peroxydisulfate to give the products in high yields. 

Direct chemical oxidation (DCO) is an ex situ treatment technology that uses acidified ammonium or sodium peroxydisulfate solutions to oxidize and destroy organic solids, liquids, and sludges. Acidified peroxydisulfate is one of the strongest oxidants available. It is equal in strength to ozone and exceeded only by fluorine and oxyfluorides. The process is designed to operate within the aqueous phase at low temperatures and ambient pressure. 

The first preparation of a silver(III) biguanide was as a result of attempts to prepare a silver(II) derivative of ethylenebis(biguanide) (91). 566 Oxidation of a silver(I) salt by sodium peroxydisulfate in the presence of the ligand, however, gave the red silver(III) derivative instead. 

Minisci s group developed homolytic substitution reactions of electron-poor arenes or hetarenes providing alkylarenes and -hetarenes extensively (see also Part 2, Sect. 2.5). The state of the art was reviewed thoroughly, so that the methodology is illustrated only by selected examples [435, 436, 437]. A protocol using silver nitrate as the catalyst and sodium peroxydisulfate as the stoichiometric oxidant proved to be very useful for the catalytic oxidative generation of radicals [438].

SODIUM PEROXYDISULFATE (7775-27-2) Noncombustible, but many chemical reactions cause fire and explosions. Reacts slowly with air, forming sodium dioxide and sodium peroxide. Elevated temperatures above 212°F/100°C cause decomposition, emitting oxygen. A strong oxidizer reacts violently with reducing agents, combustible materials, organic substances, powdered metals. Reacts with acrolein, antimony trisulfide, antimony tritelluride, arsenic pentasulfide, 1,1-dichloro-l-nitroethane, 1,3-dichloropropene, diethylamine, s-trioxane. Incompatible with /n-bis(trichlormethyl)benzene.

Ledwith and Russell (1974b) have found that chlorination of benzene, toluene and other aromatic molecules is easily achieved in aqueous acetonitrile containing sodium peroxydisulfate and copper(II) chloride. Toluene, for example, gives no benzyl chloride but a mixture of chlorotoluenes (58% o-, 4% m-, and 38% p-) consistent with the spin distribution in the toluene cation radical. The amount of copper chloride used can be catalytic provided another source of chloride ion (LiCl) is added. Reaction is attributed to the very fast transfer of chlorine atom from copper(II) chloride to the cation radical (132) the metal halide is thus regarded as a trap for the aromatic cation radical. In the absence of copper(II) chloride, reactions of toluene with peroxydisulfate ion and chloride ion give...

PANI and its derivatives can be synthesized by the electrochemical polymerization or chemical polymerization of aniline although some other approaches have also been reported such as solid-state polymerization [313], electroless polymerization [314], plasma polymerization [315], and emulsion polymerization [307], Various oxidants were used for oxidation of aniline monomer, such as ammonium peroxy-disulfate, sodium peroxydisulfate, potassium bichromate, and hydrogen peroxide.
