Brief Overview
Sodium Persulfate (or Sodium Peroxodisulfate) is a type of a white coloured inorganic compound having the formula Na2S2O8. It is the Sodium salt of the compound persulfate, it is an oxidiser, it is soluble is water however it is highly non-hygroscopic. It is most widely used for initiating polymeric reactions for styrene, acrylonitrile, etc.
Manufacturing Process
Sodium Persulphate is produced by the electrolytic oxidation of Sodium Hydrogen Sulfate. As a result, the Sodium Persulphate is concentrated, separated, and dried using vacuum crystallization or centrifugal separation technique . It can also be produced by the reaction between Ammonium Persulphate and Sodium Hydroxide in an acqueous solution. The product from the latter process exists as a crystal.
Chemical Industry
Sodium Persulfate is majorly used as a radical initiator for the production of polymers such as Styrene, Acrylonitrile, and Butadiene. It is also used for curing low formaldehyde adhesives.
Other Applications
It used as a component in bleach, detergent, etching mixtures for Zinc and circuit boards, etc. It is also used as a soil condition and for the manufacture of starch.
