Detailed Product Description:

White, crystalline powder, soluble in water.

DuPont’s trade name product, Oxone® is really a triple salt comprised

of 2KHSO5.KHSO4.K2SO4.  The active component, potassium mono-

persulfate (KHSO5, potassium peroxomonosulfate) is a salt from the

Caro´s acid H2SO5.

Grade/Purity:

This product is Reagent Grade with a minimum purity of 99%.

Background:

Potassium peroxymonosulfate, KHSO5, is widely used as an oxidizing

agent—the potassium acid salt of peroxymonosulfuric acid.

It is a component of a triple salt with the formula 2KHSO5·KHSO4·K2SO4

marketed by two companies: Evonik (formerly Degussa) under the

tradename Caroat and DuPont under the tradename Oxone—a trade

name now part of standard chemistry vocabulary.

Application Notes:

The use of Oxone has increased rapidly due to its inherent stability, the

simple handling, the non-toxic nature, the versatility of the reagent and

the relatively low cost.

As long as Oxone is stored under dry and cool conditions, it loses about

1% activity per month under release of oxygen and heat.  Decomposition

to SO2 and SO3 takes place under the influence of heat (starting at 300°C). 

Acidic, aqueous solutions of the pure reagent in distilled water are relatively

stable.  The stability reaches a minimum at pH 9, where the mono anion

(HSO5-) has the same concentration as the dianion (SO52-).  Iron, cobalt,

nickel, copper, manganese and further transition metals can catalyze the

decay of Oxone in solution.

The following secondary reactions should be avoided:  Halides can be

oxidized to halogens (e.g. chloride to chlorine), cyanides react with Oxone

under release of hydrogen cyanide, "heavy" transition metals (Cu, Mn, Co, Ni)

and their salts lead to the decomposition of Oxone under release of oxygen.

Highly efficient, mild, and simple protocols allow the oxidation of aldehydes

to carboxylic acids and esters utilizing Oxone as the sole oxidant.  These

reactions may prove to be valuable alternatives to traditional metal-mediated

oxidations.

Precautions:

Acidic, corrosive—can cause burns.  Strong oxidizing agent and fired risk

in contact with organic materials.
