IMG_262 Main physicochemical properties and technical data sheet

 

Physical properties: free flowing white powdery solid, easily soluble in water, water solubility greater than 250g/L at 20℃ (68OF). Bulk density 1.1-1.5.

 

Chemical properties: the active substance of potassium persulfate compound salt is potassium persulfate KHSO5 (or potassium persulfate). With very strong and effective non-chlorine oxidation capacity, the use and treatment process meets the safety and environmental requirements, so it is widely used in industrial production and consumption fields. Generally, it is relatively stable under the state, and decomposition reaction is easy to occur when the temperature is higher than 65℃. Relatively active, easy to participate in a variety of chemical reactions, can be used as an oxidant, bleach, catalyst, disinfectant, etching agent, etc.

Typical application cases


In the field of organic synthesis, PMPS can react with many organic substances in aqueous or solvent-aqueous solutions, for example,

• Phenols were oxidized to quinones and cycloketones to lactones by Elbus persulfate oxidation.

• PMPS aqueous solution can oxidize toluene to benzoic acid and diphenylmethane to diphenyl ketone. In the reaction, the reaction mixture must be stirred and heated backflow, because the water layer and the organic layer are insoluble.

• Pyridine can be oxidized to pyridine N oxide by PMPS mixed with glacial acetic acid, and primary aryl amine is oxidized to nitroso compound.

• Co-heating of PMPS with NaCl or NaBr can convert toluene into halogenated toluene, which is a very typical reaction. Compared with traditional persulphates, its oxidation efficiency is higher, the process is milder, the yield and quality are better.

• Under certain solvent conditions, olefins are oxidized to glycerol or glycerol ester, cyclohexene is preferentially oxidized to trans-cyclohexadiol, and epoxides are not precipitated in the PMPS/ olefins reaction system.


An example of the reaction of PMPS with olefins

Studies and literatures show that PMPS give rise to Chiral sensors in the study of asymmetric epoxidation of olefin organic catalysis. PMPS can be used as in situ reaction oxidants and catalysts to give rise to Chiral catalysts, such as Chiral imines and Chiral ketones. These are important basic oxidants to give rise to some Chiral sensors. This is because the oxidation potential of PMPS is just right.

Compared with transition metal complex catalysts, PMPS do not contain transition metals, especially heavy metals. Therefore, PMPS have important application value for many drugs.

• Initiator of polymerization reaction

Some radical initiated polymerization reactions can use PMPS as initiators, for example, polymerization of vinyl acetate, ethyl acrylate, and acrylonitrile. PMPS can also be used as initiators for polymerization of vinyl monomers. (Gansu Chemical Industry 2001, 3rd Issue, Pakiatan Journal Science, 1980,32,3-4,201)

This property can also be used in wastewater treatment containing polymers as an effective component of special flocculants. For example, building materials factories containing acrylic acid sewage treatment.
