The nature and use
of dioctyl diphenylamine in the field of chemical production raw materials
1. Introduction

dioctyl diphenylamine (DODPA) is an important organic chemical raw material, widely used in plastics, rubber, inks, coatings and other fields. In this paper, the properties and uses of dioctyl diphenylamine are introduced in detail.

2. The properties of dioctyldiphenylamine

1. Physical properties: Dioctyldiphenylamine is a light yellow or colorless transparent liquid with a special smell. It has a lower melting point, a higher boiling point, and a higher flash point and ignition point. Dioctyldiphenylamine is insoluble in water, but soluble in most organic solvents.
2. Chemical properties: dioctyl diphenylamine has good thermal stability, oxidation resistance and weather resistance. At the same time, it also has good acid and alkali resistance and oil resistance. Under high temperature conditions, dioctyldiphenylamine is not easy to decompose and can maintain good stability.

3. The use of dioctyl diphenylamine

1. Plastic additives: Dioctyl diphenylamine can be used as a plastic additive to improve the thermal stability, oxidation resistance and weather resistance of plastics. It can be widely used in polyethylene, polypropylene, polyvinyl chloride and other plastic products to extend the service life of the products.
2. Rubber antioxidant: In rubber products, dioctyldiphenylamine can be used as an antioxidant to improve the heat resistance, oxidation resistance and weather resistance of rubber, and extend the service life of rubber products.
3. Ink stabilizer: dioctyl diphenylamine can be used as an ink stabilizer to improve the heat resistance, oxidation resistance and weather resistance of the ink, and ensure the printing performance and storage stability of the ink.
4. Coating additives: In the coating, dioctyl diphenylamine can be used as an additive to improve the weather resistance, oxidation resistance and thermal stability of the coating, and extend the service life of the coating.

4. conclusion

In conclusion, as an important organic chemical raw material, dioctyldiphenylamine has been widely used in plastics, rubber, ink, paint and other fields. Because of its good thermal stability, oxidation resistance and weather resistance, dioctyldiphenylamine has become an important additive to improve product performance and prolong service life.
