Potassium peroxomonosulfate is an inorganic chemical compound of potassium from the group of sulfates and the potassium salt of peroxomonosulfuric acid .

Extraction and presentation

Potassium peroxomonosulfate can be obtained by reacting potassium carbonate or potassium hydroxide with peroxomonosulfuric acid .

{\ displaystyle {\ ce {K2CO3 + 2 H2SO5 -> 2 KHSO5 + CO2 + H2O}}}

properties

Potassium peroxomonosulfate is a crystalline white odorless solid that is readily soluble in water. It decomposes when heated above approx. 90 ° C. Its aqueous solution reacts strongly acidic. There is also a monohydrate with a monoclinic crystal structure .

use

Potassium peroxomonosulfate is used as an oxidizing agent in chemical synthesis, as a disinfectant in swimming pools, in medicine and in water treatment, as a bleaching and cleaning additive for textiles and dentures and as a caustic agent for surface treatment. It is also used to make the wool shrink-proof. The triple salt of potassium peroxomonosulfate, potassium hydrogen sulfate and potassium sulfate 2KHSO ₅ · KHSO ₄ · K ₂ SO ₄ is also sold under the name Oxone or Caroat . This is used for the halogenation of a, b-unsaturated carbonyl compounds and for the catalytic production of hypervalent iodine compounds for alcohol oxidation and for the synthesis of oxaziridines and dioxiranes such as dimethyldioxirane . This is the basis of Shi epoxidation .
