Antioxidant 1098 C40H64N2O4 Properties,Formula,Price, Uses

What is Antioxidant 1098

**Introduction to Antioxidant 1098** Antioxidant 1098 (N,N'-Bis(1,4-dimethylpentyl)-p-phenylenediamine) is a high-performance, sterically hindered phenolic antioxidant widely used in polymers, synthetic rubbers, and lubricants. It effectively inhibits oxidative degradation by scavenging free radicals, extending the service life and stability of materials exposed to heat, light, and mechanical stress. Its excellent compatibility with various substrates makes it ideal for applications in automotive, industrial, and plastic manufacturing. Antioxidant 1098 also exhibits low volatility and good resistance to extraction, ensuring long-term protection. With its superior thermal stability and non-discoloring properties, it is a preferred choice for demanding environments where durability and performance are critical.

Preparation Process: To prepare Antioxidant 1098 (N,N'-Hexane-1,6-diylbis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionamide)), follow these steps: 1. **React 3,5-di-tert-butyl-4-hydroxyhydrocinnamic acid** with **thionyl chloride** to form the corresponding acyl chloride. 2. Dissolve **hexamethylenediamine** in a solvent like dichloromethane or toluene under nitrogen. 3. Slowly add the acyl chloride solution to the diamine at 0–5°C with stirring. 4. Maintain the reaction at room temperature for 4–6 hours. 5. Filter the precipitate, wash with water, and recrystallize from ethanol or acetone. 6. Dry under vacuum to obtain pure Antioxidant 1098 as a white crystalline solid.

Usage Scenarios: Antioxidant 1098 (N,N'-Hexane-1,6-diylbis(3-(3,5-di-tert-butyl-4-hydroxyphenylpropionamide))) is a high-performance phenolic antioxidant widely used in polymers, synthetic fibers, and elastomers to prevent thermal and oxidative degradation. It effectively inhibits chain reactions caused by free radicals, extending material lifespan under heat, light, and mechanical stress. Commonly applied in polyolefins (e.g., polyethylene, polypropylene), engineering plastics, and adhesives, it offers excellent compatibility and low volatility. Its bifunctional structure provides long-term stability, making it suitable for high-temperature processing (e.g., extrusion, molding). Additionally, it is used in lubricants, coatings, and rubber products to enhance durability and performance under harsh conditions.
