Antioxidant 618 is a chemical compound commonly employed as an antioxidant and stabilizer in various industrial applications. Also known as Octadecyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, Antioxidant 618 belongs to the family of hindered phenolic antioxidants. Its primary function is to inhibit the oxidation processes that can lead to the degradation of materials such as polymers, plastics, and rubbers.
Antioxidant 618 is like a protector for materials used in different industries. It prevents these materials, like plastics and rubbers, from getting damaged due to a process called oxidation. This protector is especially good at stopping reactions that can harm the structure of these materials. By doing this, Antioxidant 618 helps these materials last longer and stay strong. It’s like a shield that keeps things in good shape, especially when they face heat and other factors that could cause damage.
Antioxidant 618 excels in extending the lifespan of materials and is especially effective in environments where protection against heat and oxidative stress is crucial. Choose UniVOOK Chemical’s Antioxidant for a trusted solution that keeps your materials in top-notch condition, enhancing their longevity and performance.

Antioxidant 618 appears as a white waxy flake solid, also known as pentaerythritol distearyl diphosphite, or pentaerythritol distearyl diphosphite.
Production process of antioxidant 618:
1- Pentaerythritol reacts with phosphorus trichloride to produce dichloropentaerythritol diphosphite, and dichloropentaerythritol diphosphite reacts with octadecyl alcohol to produce antioxidant 618;
2- By the ester reation between pentaerythritol and triphenyl phosphite to produces intermediates, and the intermediates are transesterified with octadecanol to produce antioxidant 618.
