Persulfonic acid

Polymer supported persulfonic acids can be prepared by treating polymer-bound sulfonic acids with H2O2 or K2S20g. The resulting resin was found to display an activity of 2.5 mole equivalents per gram of wet resin. This persulfonated resin was successively applied for the oxidation of carboxylic acids, ketones, olefins and for the cleavage of disulfide linkage and of A-formylamino acids. [Pg.1004]

Polymer-supported persulfonic acid was prepared from potassium persulfate and the cation exchange resin P—SO3H in water. The authors reported various applications of this new oxidizing reagent such as epoxidation of olefins, Baeyer-Villiger reaction and cleavage of disulfide and Af-formylamino acids. [Pg.1013]

When cyclohexane is irradiated with ultraviolet light in the presence of sulfur dioxide and oxygen, a heavy oil soon separates. This is evidently the persulfonic acid, whereas in the presence of acetic anhydride a crystalline mixed anhydride is obtained.88... [Pg.72]

The persulfonic acid itself decomposes into persulfonyl and hydroxyl radicals, both of which abstract hydrogen atoms from the hydrocarbons, giving further alkyl radicals that can carry on the chain ... [Pg.350]

As may be seen, the reaction is essentially a branching chain, and, when a sufficient concentration of the intermediate persulfonic acid has been built up, the reaction is self-sustaining and the source can be withdrawn. However, there are various limitations to the extent of branching, and, in particular, the water formed in the reaction can itself react with the persulfonic acid and sulfur dioxide by the reaction... [Pg.351]

As a result, losses of persulfonic acid occur, and it has been found that better utilization of the acid occurs if the reaction is deliberately altered at the acid stage by addition of the acetic anhydride as the mixed anhydride with acetic acid ... [Pg.351]
