According to Erbs persulfate oxidation method, phenol is oxidized to quinone and cyclic ketone is converted to lactone.
PMPS aqueous solution can oxidize toluene to benzoic acid and diphenylmethane to benzophenone. During the reaction, the reaction mixture must be stirred and heated to reflux, because the water layer is immiscible with the organic layer.
The mixed slurry of PMPS and glacial acetic acid can oxidize pyridine into pyridine nitrogen oxides, and aromatic primary amines can be oxidized into nitroso compounds.
The mixture of PMPS and NaCl or NaBr can be heated to convert toluene into halogenated toluene, which is a very typical reaction. Compared with traditional persulfate, it has higher oxidation efficiency, milder process and better yield and quality.
Under specific solvent conditions, olefins are oxidized to glycerol or glycerides, and cyclohexene is preferentially oxidized to trans-cyclohexanediol. In the PMPS/ olefin reaction system, there is no epoxide precipitation.
Examples of PMPS reacting with olefins
Research and literature show that PMPS can be used as oxidant and catalyst for in-situ reaction to obtain chiral catalysts-chiral imines and chiral ketones, and it is an important basic oxidant for obtaining chiral sensors. This is because the oxidation potential energy of PMPS is moderate.
Compared with transition metal complex catalysts, PMPS does not contain transition metals, especially heavy metals, so it has important application value for many drugs.
Polymerization initiator
Some free radical initiated polymerization reactions can use PMPS as initiator, for example, the polymerization of vinyl acetate, ethyl acrylate and acrylonitrile. PMPS can also be used as initiator of vinyl monomer polymerization. (Gansu Chemical Industry No.20013, Pakistan Science Journal, 1980, 32, 3-4, 20 1)
This characteristic can also be used as an effective component of special flocculant for the treatment of polymer-containing wastewater. For example, the treatment of wastewater containing acrylic acid in building materials factory.
