Description

Decylphenol CAS NO 27157-66-0 is a versatile alkylphenol compound widely used as a key intermediate in the synthesis of surfactants, lubricant additives, and polymer stabilizers. Its chemical structure, featuring a phenolic group and a long decyl chain, provides excellent surface-active properties and thermal stability, making it a critical building block for high-performance formulations. This product is essential for manufacturers in the lubricants, plastics, agrochemical, and specialty chemicals industries seeking to enhance product performance and longevity.

Application

• Surfactant & Detergent Intermediate: A primary raw material for the production of nonionic surfactants (ethoxylates) used in industrial and institutional cleaning formulations.
• Lubricant & Fuel Additive: Serves as a precursor for ashless anti-wear and antioxidant additives in engine oils, gear oils, and industrial lubricants.
• Polymer Stabilizer & Antioxidant: Used in the manufacture of phenolic antioxidants that protect plastics and elastomers from thermal and oxidative degradation.
• Agrochemical Synthesis: An intermediate in the production of certain pesticides, herbicides, and plant growth regulators.
• Resin & Epoxy Modifier: Employed to modify phenolic and epoxy resins to improve flexibility, adhesion, and chemical resistance.
• Oilfield Chemicals: A component in demulsifiers and other production chemicals used in crude oil extraction and processing.
