Useful:

• Uses: Sodium persulfate is used as a bleach, both standalone (particularly in hair cosmetics) and as a detergent component. It is a replacement for ammonium persulfate in etching mixtures for zinc and printed circuit boards, and is used for pickling of copper and some other metals. It is a source of free radicals, making it useful as an initiator for e.g. emulsion polymerization reactions and for accelerated curing of low formaldehyde adhesives. Sodium persulfate is also used as a soil conditioner and in manufacture of dyestuffs, modification of starch, bleach activator, desizing agent for oxidative desizing, etc. For waste processing in the photographic industry, used as a soft metal surface corrosion agents of the printed circuit board and textile desizing agents, sulfur dyes colorformer. Bleaching and oxidizing agent; promoter for emulsion polymerization reactions. Sodium peroxydisulfate is used as a radical initiator for emulsion polymerization reactions like acrylonitrile butadiene styrene, detergent component, soil conditioner and soil remediation. It is also used for curing of formaldehyde adhesives. It acts as a bleaching agent and in the production of dyestuffs. It finds application in zinc and printed circuit boards and considered to be a replacement for ammonium persulfate in etching mixtures. Further, it is used in the preparation of diapocynin from apocynin. It plays a role in the conversion of phenols to para-diphenols in alkaline solution and of arylamines to aminophenols. It is actively involved in the Elbs persulfate oxidation and the Boyland-Sims oxidation reactions as an oxidizing agent.

A mild and clean Baeyer-Villiger oxidation of ketones using sodium peroxydisulfate as oxidant catalyzed by silica-supported aluminum chloride

10.1007/s13738-011-0064-1

This research presents a mild and environmentally friendly method for the Baeyer–Villiger oxidation of cyclic and acyclic ketones using sodium peroxydisulfate as an oxidant and silica-supported aluminum chloride (silica-AlCl3) as a catalyst. The study investigates the preparation of the catalyst, the optimization of reaction conditions, and the application of this catalytic system to various ketones. The results demonstrate that the use of sodium peroxydisulfate as an oxidant leads to higher yields and selectivity compared to traditional methods using hydrogen peroxide. The catalyst can be easily separated by filtration and reused for multiple cycles with reasonable activity retention. The mild reaction conditions and high product yields make this method a promising candidate for industrial applications, offering a green alternative to conventional Baeyer–Villiger oxidation processes.
