Description

4-n-Octadecylphenol is a high-purity, long-chain alkylphenol derivative, also known as 4-Octadecylphenol. This compound serves as a critical intermediate and functional additive, valued for its hydrophobic alkyl chain and reactive phenolic group. It is essential for manufacturers in the polymer, surfactant, and specialty chemical industries seeking to modify material properties or synthesize advanced chemical products.

Application

• Polymer Additive & Stabilizer: Acts as an antioxidant and processing stabilizer in plastics and rubber formulations.
• Surfactant & Detergent Intermediate: Used in the synthesis of nonionic surfactants (alkylphenol ethoxylates) for industrial and institutional cleaning products.
• Lubricant & Fuel Additive: Functions as a dispersant, viscosity modifier, or anti-wear agent in lubricating oils and fuel formulations.
• Chemical Synthesis Intermediate: A key building block for producing oil-soluble resins, phenolic antioxidants, and other specialty alkylated phenols.
• Coating & Ink Formulations: Imparts hydrophobicity and improves adhesion properties in specific coating and ink systems.
• Research & Development: Serves as a standard or reagent in organic synthesis and material science research.
