Antioxidant 565 Chemical Properties,Uses,Production

Description

Antioxidants are a class of chemicals that, when present only in small quantities in a polymer system, can slow or inhibit the oxidation of the polymer, thereby preventing the polymer from aging and extending its service life. They are also called "antiaging agents". Antioxidant 565, chemical name of which is 6-(4-hydroxy-3, 5-ditert-butyl phenyl amino)-2, 4-din-n-octyl sulfide -1, 3, 5-triazine, is white crystalline powder, soluble in many organic solvents, insoluble in water.

Application

Antioxidant 565 is a kind of macromolecule, which was a multi-function blocked phenolic antioxidant. Mainly, antioxidant 565 is suitable for the post-processing and stable treatment of unsaturated rubber. It can protect the material from thermal oxidation degradation in the process of production, processing as well as final use. At the same time, antioxidant 565 is a variety of excellent resin antioxidants and photothermal stabilizer, with small addition, low volatility, high color fastness, and can prevent the formation of gel characteristics. Traditionally, antioxidant 565 is a highly effective antioxidant used in a variety of elastomers, including polybutadiene (BR), polyisoprene (IR), latex styrene-butadiene rubber (SBR), nitrile rubber (NBR), carboxylate SBR latex (XSBR), styrene block copolymers such as SBS and SIS. Antioxidant 565 is also used for adhesives (hot melt solvent-based), natural and synthetic viscosifying resins, epdm, ABS, impact resistant polystyrene, polyamide, and polyolefin.

Chemical Properties

Antioxidant 565 is a highly effective antioxidant. It prevents gel formation, changes to molecular weight and maintains excellent polymer color in unsaturated elastomers. This grade is highly effective at low concentrations and matches the performance of other stabilizers at higher levels. It exhibits non-staining and low volatility. It allows easy dispersion due to low melting point in elastomeric substrates using melt compounding techniques. It can be incorporated into process streams by dissolving in suitable organic solvents or aromatic extender oils.

Definition

ChEBI: 4-((4,6-bis(octylthio)-1,3,5-triazin-2-yl)amino)-2,6-di-tert-butylphenol is a member of triazines.

Flammability and Explosibility

Not classified

Synthesis

By taking 2,6-di-tert-butylphenol as the raw material, and then adding sodium nitrite solution dropwise to form an intermediate product of 2,6-di-tert-butyl-4-nitrosophenol solution, with the added Rayon Nickel is used as a catalyst and carbon monoxide is used instead of hydrogen as a reducing agent to overcome hydrogen as a reducing agent. The pressure in the hydrogenation process is high, which is prone to explosion problems. At the same time, iron crystals are added to remove excess carbon monoxide and avoid the effects of carbon monoxide toxicity. The impurities are removed by filtration, and other by-products will not be formed, which can greatly increase the yield of antioxidant 565, and the product purity is high.
