classification
    

1, aromatic amine antioxidant
    

Aromatic amine antioxidant, also known as rubber antioxidant, is the largest number of production of a class, such antioxidants low price, antioxidant effect is significant, but because of the products discoloration, limiting their light and white products Applications, mainly used in plastics, synthetic fibers, latex, petroleum products, food, medicine and cosmetics. Important aromatic amine antioxidants are: diphenylamine, p-phenylenediamine and dihydroquinoline and other compounds and their derivatives or polymers, can be used in natural rubber, styrene butadiene rubber, chloroprene rubber and isoprene rubber and other products in.
  

 2, hindered phenolic antioxidants
  

 Hindered phenolic antioxidants are some of the hindered phenolic compounds, their thermal oxidation effect is significant, will not pollute products, the rapid development. There are many varieties of these antioxidants, the important products are: 2,6-tertiary butyl-4-methyl phenol, bis (3,5-tertiary butyl-4-hydroxyphenyl) [? - (3,5-tri-butyl-4-hydroxyphenyl) propionic acid] pentaerythritol ester. Such antioxidants are mainly used in plastics, synthetic fibers, latex, petroleum products, food, medicine and cosmetics.

3, auxiliary antioxidant
   

Thiodipropionic acid diester is a kind of auxiliary antioxidant, often with hindered phenolic antioxidants and use, the effect is significant, such as: thiodipropionic acid diester, often with hindered phenolic antioxidants and the effect is significant , The main products are: double dodecanol ester, double tetradecyl alcohol ester and octacosanol ester.
   

 Phosphite is also a secondary antioxidant, the main products are: three octyl ester, three decyl ester, three (dodecyl alcohol) ester and three (hexadecyl alcohol) ester.
