Dioctyldiphenylamine (DODPA) is an important chemical raw material, which is widely used in rubber, plastic, ink and other fields. The upstream and downstream associated products of DODPA mainly include the following categories:

1. Upstream raw material

(1) Aniline: Aniline is one of the important raw materials of DODPA, which is used to react with octyl compounds to generate DODPA. The production methods of aniline mainly include nitrobenzene reduction method, benzene hydroxylamine method and so on.

(2) Octyl Compound: The octyl compound is another important raw material of DODPA, and is usually octanol or octanoic acid. These compounds can be produced by processes such as petroleum cracking, fatty acid esterification, and the like.

2. Downstream product

(1) Antioxidant: DODPA can be used as an antioxidant for rubber, plastics and other polymer materials to improve its anti-oxidation, anti-ozone and other properties and extend its service life. Common antioxidant products include antioxidant 4010, antioxidant 4020, etc.

(2) Antioxidant: DODPA can also be used as an antioxidant in plastics, inks and other fields to prevent oxidative degradation of materials during processing and use. Common antioxidant products include antioxidant 1010, antioxidant 1076, etc.

(3) flame retardant: DODPA can be used as a synergistic agent of flame retardant to improve the flame retardant performance of materials. Common flame retardant products include decabromodiphenyl ether and tetrabromobisphenol A.

In short, as an important raw material for the production of chemical products, dioctyl diphenylamine has a wide range of upstream and downstream related products, involving many fields, such as rubber, plastics, ink and so on.
