Description

3-Undecylphenol is a high-purity alkylphenol derivative characterized by its long aliphatic chain attached to a phenolic ring. This unique structure makes it a valuable nonionic surfactant intermediate and a versatile building block for specialty polymers and additives. It is primarily utilized by manufacturers in the lubricant, agrochemical, and polymer industries seeking to enhance product performance through tailored surface activity and chemical resistance.

Application

• Surfactant & Detergent Intermediate: A key raw material for synthesizing nonionic surfactants (e.g., ethoxylates) used in industrial cleaners, emulsifiers, and wetting agents.
• Lubricant & Fuel Additive: Serves as a precursor for antioxidants, dispersants, and viscosity index improvers in engine oils and industrial lubricants.
• Polymer Stabilizer & Plasticizer: Used in the production of phenolic resins, epoxy curing agents, and as a stabilizer/plasticizer component for PVC and other polymers.
• Agrochemical Formulations: Acts as an intermediate in the synthesis of pesticides, herbicides, and adjuvants that improve the efficacy of crop protection products.
• Oilfield Chemicals: Employed in the formulation of demulsifiers and corrosion inhibitors for crude oil processing and drilling fluids.
• Chemical Synthesis: A versatile alkylating agent and hydrophobic modifier in organic synthesis for pharmaceuticals and specialty chemicals.
