Potassium peroxydisulfate (potassium persulfate) [7727-21-1] M 270.3. Crystd twice from distilled water (lOmL/g) and dried at 50° in a vacuum desiccator. [Pg.456]

Photolysis or thermolysis of persulfate ion (41) (also called peroxydisulfate) results in hoinolysis of the 0-0 bond and formation of two sulfate radical anions. The thermal reaction in aqueous media has been widely studied."51 232 The rate of decomposition is a complex function of pH, ionic strength, and concentration. Initiator efficiencies for persulfate in emulsion polymerization are low (0.1-0.3) and depend upon reaction conditions (Le. temperature, initiator concentration)."33... [Pg.94]

Several powerful oxidants can be easily removed after preoxidation. Peroxydisulfate (S20, also called persulfate) is a strong oxidant that requires Ag+as a catalyst. [Pg.335]

Toluene has been oxidized by the silver ion catalysed reaction with peroxy-disulfate. The reaction produces a mixture of bibenzyl, benzaldehyde and benzoic acids.299 Russian workers have described the conversion of 4-methoxy-toluene to the benzaldehyde by oxidation with peroxydisulfate in the presence of silver or copper ions and oxalic acid.300 The presence of copper salts in iron or copper catalysed peroxydisulfate oxidation is believed to suppress side-reactions.301 Phillips have patented a palladium(II)/tin(IV)/persulfate system for the oxidation of toluene derivatives.302 The reactions are carried out in carboxylic acid solvents (Figure 3.78). [Pg.139]

Mechanism The nucleophilic attack of phenoxide through para position of the aromatic ring carbon on the peroxide oxygen of the peroxydisulfate ion forms the intermediate persulfate 7.44. Hydrolysis of 7.44 gives the p-hydroquinone 7.30. [Pg.291]

Homogeneous oxidants Peroxydisulfate ion, S20g (often called persulfate), is a strong oxidant in acid solution in the presence of silver ion as catalyst. The reaction... [Pg.308]
