General description

Ammonium persulfateis a readily available oxidizing agent for various chemicaltransformations, and it is also usedas a bleaching agent in the chemical industry.

Application

Ammonium persulfate can be used as an oxidizing reagent for the solvent-free oxidation of:
  • Primary and secondary alcohols to corresponding carbonyl compounds in an aqueous medium.
  • Thiols to disulfides.
It can also be used as an initiator to initiate copolymerization of acrylonitrile and itaconic acid.
Catalyst for acrylamide gel polymerization.
