Description

n-Tetradecylphosphonic Acid is a high-purity, long-chain organophosphorus compound that serves as a critical building block and surface modifier. Its molecular structure, featuring a 14-carbon alkyl chain terminated by a phosphonic acid group, provides excellent chelating and self-assembling properties. This makes it indispensable for researchers and manufacturers in advanced material science, particularly for creating corrosion-resistant coatings, functionalizing metal oxide surfaces, and developing novel extraction agents.

Application

• Surface Modification & Corrosion Inhibition: Forms stable, self-assembled monolayers (SAMs) on metal oxides (e.g., steel, aluminum, titanium) to enhance corrosion resistance and alter surface wettability.
• Lubricant & Fuel Additive: Acts as an anti-wear and extreme pressure (EP) additive in industrial lubricants and functional fluid formulations.
• Metal Extraction & Separation: Used as an extractant or chelating agent in solvent extraction processes for the separation and recovery of rare earth and transition metals.
• Polymer Additive & Flame Retardancy: Incorporated into polymer matrices as a stabilizer or to impart flame-retardant characteristics.
• Nanomaterial Functionalization: Key ligand for surface passivation and functionalization of nanoparticles (e.g., quantum dots, iron oxide NPs) to improve dispersion and biocompatibility.
• Adhesion Promotion: Improves the adhesion of paints, coatings, and adhesives to metallic substrates by forming a strong chemical interface.
