Potassium peroxy disulfate

The surface of polymeric materials such as polypropylene (PP), PS, polyacrylonitrile (PAN), and nylon was oxidized by immersing them in aqueous solution of oxidizing agents such as potassium peroxy disulfate under nitrogen purging at high temperatures [14]. Graft polymerization of water-soluble monomers such as AAm, methacrylic acid, and 3-aminopropyl methacrylate has been frequently performed in aqueous solution with the use of ceric ion, for instance, at...

Copper sulfate, CuS04 5H20, is used for the oxidative coupling of terminal acetylenes [5S] for the conversion of a-hydroxy ketones (acyloins) into a-diketones [351, 352] and, in cooperation with potassium peroxy-disulfate, for the selective oxidation of methyl groups on benzene rings to aldehyde groups [355],... 

The regiospecific oxidation of dimethylanisoles to methoxymethyl-benzaldehydes is accomplished with copper sulfate and potassium peroxy-disulfate, which oxidize selectively only the methyls in the ortho or para positions with respect to the methoxy group (equation 171) [35J]. 

A homologous series of a,co-perfluorodicarboxylic acids (n= 1-16) were recently synthesized by a controlled free radical polymerization of tetrafluoroethylene using aqueous potassium peroxy-disulfate with either an iron or copper promoter. The dominant products were the even-numbered members, as demonstrated by the proposed mechanism in Scheme 26. It was shown that the odd-numbered carbon chains result from oxidative decarboxylation. 

Redox reactions involving peroxides are another ejBhcient way to prepare telechelics. Hydroxyl-terminated polydienes [37] and carboxylic acid-terminated polytetrafluoroethylenes [38] were synthesized by using H2O2 and potassium peroxy disulfate, respectively, via redox reactions.

Interestingly, persulfate reacts differently with aliphatic and aromatic amines. Aliphatic primary amines are dehydrogenated to imines and further converted to aldehydes when reacted with peroxy disulfate , whereas aromatic primary amines are oxidized to nitroso compounds using potassium persulfate in the presence of H2SO4 (equation 14) °. 

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.
