Properties of Sebacic Acid

sebacic acid (Decanedioic acid), the chemical formula is C10H18O4, is an aliphatic dibasic acid, usually present as a white or light yellow crystalline powder. It has excellent chemical stability and thermal stability, with a melting point of 130-134°C, a boiling point of 330°C, and low volatility at room temperature. Sebacic acid is soluble in alcohol and ether solvents, but its solubility in water is low. These properties make it widely used in chemical industry.

Use of sebacic acid

the use of sebacic acid is mainly concentrated in the following aspects:

production of high-performance nylon materials: Sebacic acid is the main raw material of nylon 610 and nylon 1010. These nylon materials are widely used in the fields of engineering plastics and fibers due to their excellent mechanical properties and chemical resistance.
plastic plasticizer sebacate plasticizers are widely used in the manufacture of durable plastic products due to their low volatility and high molecular weight.
Lubricating oil and grease: Sebacates are also used in the production of synthetic lubricants and greases, with excellent low temperature properties and oxidation resistance.
Coatings and adhesives: Due to its excellent chemical stability, sebacic acid is used to produce high-performance coatings and adhesives, providing good adhesion and weather resistance.

Upstream raw material of sebacic acid

the production of sebacic acid is mainly realized by chemical synthesis, and its upstream raw materials include:

dimethyl sebacate as a precursor of sebacic acid, dimethyl sebacate is produced by hydrolysis.
Decene: An unsaturated hydrocarbon compound with a long carbon chain that produces sebacic acid by oxidation.
Castor oil: Sebacic acid is generated by a cracking reaction, which is an example of green chemical synthesis, using renewable resources to achieve sebacic acid production.

Downstream products of sebacic acid

the downstream products of sebacic acid mainly include:

nylon 610 and Nylon 1010: These high-performance nylon materials have a wide range of applications in the field of engineering plastics and fibers.
sebacate plasticizer: Used to manufacture high-durability plastic products, such as cables, films, etc.
Synthetic lubricants and greases: Used in aviation, automotive and industrial equipment to provide excellent lubrication and wear resistance.
High performance coatings and adhesives: Provides excellent chemical and weather resistance for applications in the construction, automotive and electronics industries.

Storage method of sebacic acid

as a chemical, the storage method of sebacic acid requires special attention to the following aspects:

environmental Control: Sebacic acid should be stored in a cool, dry, well-ventilated environment, avoid direct sunlight and high temperature environment to prevent its decomposition and volatilization.
Container Selection: Containers with good airtightness, such as plastic barrels or metal barrels, should be used to avoid long-term contact with air to prevent moisture absorption and oxidation.
Fireproof and explosion-proof: Although sebacic acid itself is not flammable, its dust may form an explosive mixture under certain conditions, so dust accumulation should be avoided and kept away from fire and heat sources.
Safety identification: The storage area should have a clear safety mark, indicating the chemical properties of sebacic acid and emergency treatment measures to ensure that operators understand its potential risks.

Conclusion

as an important chemical raw material, sebacic acid has excellent physical and chemical properties and a wide range of applications. Through reasonable raw material selection and production process, high purity sebacic acid can be effectively produced, and used in nylon, plasticizer, lubricants and coatings and other fields. During storage and transportation, appropriate measures need to be taken to ensure the quality and safety of sebacic acid. With the development of chemical technology and the promotion of the concept of green chemical industry, the production and application of sebacic acid will usher in a broader development prospects.
