Peroxygen reaction with activators

Hydrogen peroxide, when supplied commercially, is usually stabilized with phosphates and tin(IV) materials. The tin compounds are effective at the product s natural pH via hydro-colloid formation, which adsorbs transition metals and reduces their catalytic activity. In the majority of cases, extra stabilization is not required when hydrogen peroxide or its derivatives are used in synthesis. Elevated temperatures and increased metal impurities all tend to destabilize peroxygens, and where such conditions are unavoidable, additional stabilizers may be employed, added either to the hydrogen peroxide or the reaction mixture separately. Stabilizer type falls into two categories seques-trants and radical scavengers. [Pg.72]
