Read： 366 Time：20months ago Source：Transform the World with Simplicity

n-decanoic acid is a saturated fatty acid with a molecular formula of C10H20O2 and a molecular weight of 172.26. It is a colorless to yellowish transparent liquid with an elegant fatty odor. Decanoic acid is chemically stable, insoluble in water, but soluble in ethanol, ether and other organic solvents. It has a melting point of -3.5°C, a boiling point of 253°C and a flash point of 121°C. N-decanoic acid is not harmful to the environment, and special attention should be paid to water bodies.

decanoic acid has a wide range of applications in the field of chemical production raw materials. First of all, it can be used as a plastic plasticizer, which can increase the plasticity, flexibility and ductility of plastics, and improve the processing performance and service life of plastic products. Secondly, decanoic acid can also be used as a raw material for rubber accelerators, which can increase the vulcanization rate and crosslinking density of rubber, and improve the mechanical properties and aging resistance of rubber products. In addition, decanoic acid can also be used as an additive for lubricating oil, which can improve the lubricating performance and oxidation resistance of lubricating oil and prolong the service life of lubricating oil.

In the production process of n-decanoic acid, safety measures need to be paid attention. Operators must be specially trained and strictly abide by the operating procedures. Ventilation facilities and fire-fighting facilities shall be set at the production site to ensure production safety. At the same time, during the storage and transportation of n-decanoic acid, it is also necessary to keep the container sealed, avoid contact with the oxidant, and store it in a cool and ventilated warehouse, away from fire and heat sources.

In conclusion, decanoic acid as an important raw material for chemical production has a wide range of uses and good properties. In the process of production and use, it is necessary to pay attention to safety and environmental protection requirements to ensure product quality and efficiency.
