Potassium Monopersulfate Triple Salt [Oxone^®]

Introduction

Potassium monoperoxysulfate triple salt (·2KHSO₅· KHSO₄·K₂SO₄] is available as ‘Oxone’ (Dupont registered name). Oxone^® is a white, granular and free flowing solid. It is soluble in water and insoluble in common organic solvents. It has a low order of toxicity. Traces of heavy metal salts catalyze the decomposition of Oxone. This triple salt is a convenient and stable form of the unstable potassium monopersulfuric acid (Caroate). In situ genereated unstable caroate serves as a stoichiometric oxidizing agent for a number of functional groups including alkenes, arenes, amines, imines, sulfides, and is used for the preparation of dioxaranes under a variety of conditions. Oxone is used for the cleavage of acetals, ketals and also for the dehydration of oximes.
