Description

Dinonyl Phenol is a high-molecular-weight alkylphenol produced by the alkylation of phenol with nonene. This compound serves as a versatile chemical intermediate and functional additive, valued for its hydrophobic character and phenolic functionality. It is primarily utilized in the production of surfactants, lubricant additives, and polymer stabilizers across the chemical manufacturing, plastics, and oilfield industries.

Application

• Key intermediate in the synthesis of nonionic surfactants (e.g., ethoxylates) for industrial and institutional cleaning formulations.
• Production of lubricant and fuel oil additives, where it acts as an antioxidant and detergent/dispersant precursor.
• Manufacture of phenolic resins and epoxy resin modifiers, enhancing flexibility and hydrophobic properties.
• Stabilizer and antioxidant component in polymers and plastics to prevent thermal and oxidative degradation.
• Raw material for the production of phosphite antioxidants used in polymer processing.
• Intermediate for oil-soluble phenolic antioxidants in industrial greases and hydraulic fluids.
• Chemical building block in specialty adhesives and sealants requiring hydrophobic phenols.
• Precursor for ion-exchange resins and other specialty chemicals in water treatment applications.
