The acid is prepared by the reaction of chlorosulfuric acid with hydrogen peroxide: [3]. 2 ClSO 3 H + H 2 O 2 → H 2 S 2 O 8 + 2 HCl. Another method is the electrolysis of moderately concentrated sulfuric acid (60-70%) with platinum electrodes at high current density and voltage:
The peroxydisulfate ion, S 2 O 2− 8, is an oxyanion, the anion of peroxydisulfuric acid.It is commonly referred to as persulfate, but this term also refers to the peroxomonosulfate ion, SO 2−
The linkage between the oxygen molecules is known as a peroxy group (sometimes called peroxo group, peroxyl group, of peroxy linkage). The nomenclature of the peroxy group is somewhat variable, [ 4 ] and exists as an exception to the rules of naming polyatomic ions.
One laboratory scale preparation of Caro's acid involves the combination of chlorosulfuric acid and hydrogen peroxide: [6]. H 2 O 2 + ClSO 2 OH ⇌ H 2 SO 5 + HCl. Patents include more than one reaction for preparation of Caro's acid, usually as an intermediate for the production of potassium monopersulfate (PMPS), a bleaching and oxidizing agent.
The concept of active oxygen content is useful for comparing the relative concentration of peroxy groups in formulations, which is related to the energy content. In general, energy content increases with active oxygen content, and thus the higher the molecular weight of the organic groups, the lower the energy content and, usually, the lower ...
Lipid peroxidation, or lipid oxidation, is a complex chemical process that leads to oxidative degradation of lipids, [1] resulting in the formation of peroxide and hydroperoxide derivatives. [2] It occurs when free radicals , specifically reactive oxygen species (ROS), interact with lipids within cell membranes , typically polyunsaturated fatty ...

The described process is suitable for the pilot scale production of sodium peroxodicarbonate. Potassium peroxydicarbonate K 2 C 2 O 6 was obtained by Constam and von Hansen in 1895; [6] its crystal structure was determined only in 2002. [7] It too can be obtained by electrolysis of a saturated potassium carbonate solution at −20 °C.
