Chemical Name: oxone, potassium monopersulfate compound, potassium monopersulfate triple salt or potassium peroxymonopersulfate
For short name: PMPS or KMPS DuPont name: oxone. Degussa name: caroat
Molecular formula: 2KHSO5KHSO4K2SO4
Molecular weight: 614.7
CAS No. 70693-62-8 UN 3260

Physical properties:potassium monopersulfate compound is a free-flowing, white granular solid, soluble in water. Under 20°C, 68°F temperature, solubility (20°C) >250g/l. bulk density: 1.1-1.2


Chemical properties:the active substance is potassium monopersulfate compound, KHSO5. The compound provides powerful and effective non-chlorine oxidation for a wide variety of industrial and consumer uses while treatment process meet the requirements of safety and environment protection. It is stable under normal condition but dissolved above 80 deg centigrade. KMPS is active to react with other chemicals as it can be the oxidizer, bleacher, catalyst, disinfector and etchant etc.
