Potassium perphosphate

Potassium perphosphate gives with silver nitrate a dark precipitate which changes to white AgsPOs, then to yellow Ag3P04 with evolution of ozone and oxygen. 

There are several peroxygen derivatives that occasionally find use in textile industry. These are potassium peroxymonosulphate (monopersulphate), potassium perphosphate and urea peroxide. These compounds are rarely used by themselves, but are used primarily as bleach boosters. They are all powders and are usually compounded where a strong colourless oxidising agent is indicated. The mechanism of potassium peroxydisulphateperoxide is represented by the following reactions ... 

In the work conducted by Chandrasekaran, " initiators for solvent-based polymerization included aliphatic and aromatic peroxy compounds, including fluorine and chlorine substituted organic peroxides. Specific examples are acetyl peroxide, succinic acid peroxide, 2,4-dichlorobenzoyl peroxide, t-butylper-oxypivalate, decanoyl peroxide, trichloroacetyl peroxide, and perfluoropropionyl peroxide. Aqueous polymerization was conducted using persulfate, perphosphate and perborate salts of sodium, potassium.
