High Quality Content by WIKIPEDIA articles! Potassium peroxymonosulfate (also known as MPS, potassium monopersulfate, and the trade names Caroat and Oxone) is widely used as an oxidizing agent. It is the potassium salt of peroxymonosulfuric acid. The potassium salt is marketed by two companies: Evonik (formerly Degussa) under the tradename Caroat and DuPont under the tradename Oxone, tradenames which are now part of standard chemistry vocabulary. It is a component of a triple salt with the formula 2KHSO5·KHSO4·K2SO4. The standard electrode potential for this compound is -1.44 V with a half reaction generating the hydrogen sulfate. Oxone is a versatile oxidant. It oxidizes aldehydes to carboxylic acids; in the presence of alcoholic solvents, the esters may be obtained. Internal alkenes may be cleaved to two carboxylic acids, while terminal alkenes may be epoxidized. Thioethers give sulfones, tertiary amines give amine oxides, and phosphines give phosphine oxides.
