The application of potassium persulfate(K2S2O8) in chemical synthesis is mainly reflected in its properties as a strong oxidizing agent, which can promote a variety of chemical reactions. The
following is the specific application of potassium persulfate in chemical synthesis:
1. Polymerization initiator: Potassiumpersulfate is used as the initiator of emulsion polymerization in the synthetic resin and synthetic rubber industry, especially in the emulsion polymerization of butadiene-styrene (BS). It produces free radicals to initiate polymerization
reactions, resulting in the synthesis of various polymers.
2. Synthetic hybrid polymer flocculant:Potassium persulfate and azodiisobulimidazoline hydrochloride (VA-044 initiator) composite initiation system can be used to synthesize
polythioaluminum chloride polyacrylamide (PACS-PAM) hybrid polymer flocculant. This
flocculant has important applications in water treatment and other fields.
3. Oxidant: Potassium persulfate is used asan oxidant in organic synthesis for REDOX reactions, such as epoxidation, hydroxylation, etc. For example, potassium persulfate can be used for high
efficiency air epoxidation of olefins.
4. Synthesis of N and S co-doped carbonnanosheets: Potassium persulfate is an effective activator for the synthesis of N and S co-doped carbon nanosheets (N, S-CNSS) from renewable onion. The material has potential applications in electrochemical energy storage devices.
5. Oil well fracturing fluid gumming agent:potassium persulfate can be used as the gumming agent of oil well fracturing fluid, which helps to improve the efficiency of oil and gas exploitation.
6. Synthetic sodium thiosulfate remover: Inthe photographic industry, potassium persulfate is used as a sodium thiosulfate remover, which helps to improve the quality and stability of the film.
7. Oxidant in dyes and printing and dyeingindustry: Potassium persulfate is used as oxidant in dyes and printing and dyeing industry for textile dyeing and printing process.
These applications demonstrate thediversity and importance of potassium persulfate in chemical synthesis, not only to facilitate the conduct of multiple chemical reactions, but also to
provide specific chemical functions in specific fields. With the development of chemical synthesis technology, the application of potassium persulfate in the field of chemical synthesis may be further expanded and deepened.
