Potassium persulfate

[1][4] It can also be prepared by adding potassium bisulfate (KHSO4) to a solution of the more soluble salt ammonium peroxydisulfate (NH4)2S2O8.

In principle it can be prepared by chemical oxidation of potassium sulfate using fluorine.

Several million kilograms of the ammonium, sodium, and potassium salts of peroxydisulfate are produced annually.

This salt is used to initiate polymerization of various alkenes leading to commercially important polymers such as styrene-butadiene rubber and polytetrafluoroethylene and related materials.

[7] It has been used as an improving agent for flour with the E number E922, although it is no longer approved for this use within the EU.
