Description

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.
