Sodium persulfate

Molecular formular: Na2S2O8

Molecular weight: 238.13


Sodium persulfate is a white, crystalline, odourless salt. It is used as initiator for the polymerisation of monomers and as a strong oxidizing agent in many application. It has the particular advantage of being almost non-hygroscopic, of having a particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.

Storage: Sodium persulfate is not combustible, but assists combustion of combustible materials due to release of oxygen. It must be stored in a dry location away from heat and a cool, well ventilated area away from all sources of ignition and out of direct sunlight, protected from moisture. Keep containers tightly closed, labeled and well sealed. Ensure pressure relief and adequate ventilation. It must be stored separately from organics, rust or traces of metal, reductions and others incompatible materials to avoid catalytic decomposition.
