Soluble in water. Insoluble in alcohol.


Potassium peroxydisulfate is used as an oxidizing agent in organic synthesis. It is involved in the Elbs persulfate oxidation of phenols and the Boyland-Sims oxidation of anilines. In solution, it gives radicals and is used to initiate polymerization reactions to prepare styrene-butadiene rubber and polytetrafluoroethylene. It is used as a bleaching agent in various hair bleaches, as an ion exchange agent, a plating agent and a surface treating agent.


Moisture sensitive. Incompatible with organic materials, strong reducing agents, powdered metals, strong bases, alcohols, phosphorous, anhydrides, halogens and acids.


Useful oxidant: J. Org. Chem., 25, 1901 (1960); examples:

Conversion of phenols to para-diphenols in alkaline solution (Elbs oxidation), and of arylamines to aminophenols (Boyland-Sims oxidation); review: Org. React., 35, 421 (1988). Phase-transfer conversion of acids to peracids in the presence of BTEAC or PEG: Synth. Commun., 18, 2123 (1988). In the presence of Na2HPO4 in acetone - dichloromethane, arylamines give nitro arenes: Tetrahedron Lett., 29, 4501 (1988). In the presence of Ni(II) salts, primary alkylamines can undergo dehydrogenation to nitriles: Bull. Chem. Soc. Jpn., 63, 301 (1990).
