Description

Tri-Hexadecylamine is a high-purity, long-chain tertiary amine with the CAS number 28947-77-5. This compound serves as a versatile intermediate and functional additive, valued for its surfactant properties and ability to act as a phase-transfer catalyst or corrosion inhibitor. It is essential for industrial and research applications where a strong, lipophilic base or a hydrophobic amine functionality is required.

Application

• Surfactant & Emulsifier: Acts as a key component in the formulation of industrial detergents, emulsifiers, and demulsifiers for oilfield and agrochemical applications.
• Chemical Intermediate: Used in the synthesis of quaternary ammonium compounds (quats), amine oxides, and other specialty chemicals for personal care and biocides.
• Corrosion Inhibitor: Employed in fuel and lubricant additive packages to protect metal surfaces in harsh environments.
• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly useful in organic synthesis and polymer manufacturing.
• Extraction Agent: Utilized in solvent extraction processes for the purification and recovery of metals and organic acids.
• Fabric Softener & Antistatic Agent: A precursor for cationic surfactants used in textile treatment and fabric conditioning.
