[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods of ammonium persulfate, and what role ammonium persulfate plays

Ammonium persulfate properties

Ammonium persulfate (Ammonium Persulfate,APS) is an inorganic compound with the chemical formula (NH4)2S2O8. It usually appears as white crystals or powder, with strong oxidation. It has good solubility, is easily soluble in water, and can form free radicals in aqueous solution. Thus, ammonium persulfate is used as a strong oxidant and free radical initiator in many chemical reactions. It has a high decomposition temperature and releases oxygen and ammonia when heated.

Ammonium persulfate uses

Ammonium persulfate is widely used in many fields due to its strong oxidation and free radical generating ability.

Polymerization Initiator: Ammonium persulfate is commonly used in the polymerization of vinyl monomers, such as polyacrylate, polystyrene, polyvinyl chloride, etc. The free radicals generated by its decomposition in aqueous solution can initiate the polymerization of monomers to form high molecular polymers.

Textile industry bleach: ammonium persulfate for textile bleaching, can effectively remove dyes and impurities, make textiles more white and pure.

Electronics Industry Cleaning Agents: Ammonium persulfate is used to clean and etch printed circuit boards in the electronics industry. Its oxidation can remove oxides and impurities on the metal surface to ensure the cleanliness and functionality of the circuit board.

Sewage Disinfectant: Ammonium persulfate can be used in sewage treatment due to its strong oxidation, which can disinfect and remove organic pollutants.

Ammonium persulfate upstream and downstream raw materials

Upstream raw materials:

Sulfuric acid: An important raw material for the production of ammonium persulfate is sulfuric acid. The high-purity sulfuric acid reacts with the ammonium salt during the reaction to form ammonium persulfate.

Ammonium salts: Ammonium salts, such as ammonia or ammonium sulfate, are another key raw material for the production of ammonium persulfate. These ammonium salts react with sulfuric acid to form ammonium persulfate.

Electricity: The electrolysis process in the production process requires a large amount of electricity, so electricity cost and supply are also important factors in the production of ammonium persulfate.

Downstream Products:

Polymers: Ammonium persulfate is widely used to initiate polymerization, so its downstream products are mainly a variety of polymers, such as plastics, rubber and fibers.

Bleaching and cleaning products: Ammonium persulfate is used in the textile and electronics industries to produce bleaching and cleaning agents, which are used in textile treatment and electronic component cleaning.

Wastewater Treatment Products: Ammonium persulfate is used in the wastewater treatment sector to produce disinfectants and oxidizers that help remove contaminants and pathogens from water.

Ammonium persulfate storage method

Sealed container: Ammonium persulfate is hygroscopic and decomposable, it is necessary to use a sealed container during storage to prevent moisture and contamination.

Avoid light preservation: Ammonium persulfate is easy to decompose under light, so it needs to be stored in the dark, preferably in a cool and dry place.

Prevent high temperature: high temperature will accelerate the decomposition of ammonium persulfate, so the temperature of the storage environment should be kept within an appropriate range, usually no more than 30 degrees Celsius.

Fire prevention and explosion prevention: ammonium persulfate has strong oxidation, and should be kept away from flammable and explosive materials in storage and use to prevent fire or explosion accidents.

Market Analysis

Demand growth: With the process of industrialization and urbanization, the demand for ammonium persulfate is increasing. Especially in the fields of chemical industry, electronics and sewage treatment, the demand for efficient oxidants and initiators has promoted the development of the market.

Technological progress: The improvement of production process and technological progress have improved the production efficiency and product purity of ammonium persulfate, reduced production costs, and promoted the expansion of the market.

Environmental policy: Increasingly stringent environmental policies around the world have also promoted the use of ammonium persulfate. Due to its role in sewage treatment and environmental cleaning, the ammonium persulfate market has been positively affected by the policy.

Conclusion

As an important chemical raw material, ammonium persulfate has a wide range of applications and good market prospects. Its strong oxidation and free radical generation ability make it play an important role in the fields of polymerization, textile bleaching, electronic cleaning and sewage treatment. By optimizing the production process and strengthening the safety management, the production and application benefits of ammonium persulfate can be further improved. In the future, with the demand for environmental protection and technological progress, the market for ammonium persulfate will continue to grow steadily.
