Description

Di-9-Octadecenyl Hydrogen Phosphate is a high-purity organophosphorus compound, also known as dioleyl hydrogen phosphate. This specialty chemical serves as a highly effective anionic surfactant and metal extraction agent, valued for its unique amphiphilic properties. It is primarily utilized in advanced industrial applications where precise surface modification and selective ion chelation are required. Key sectors include lubricant formulation, polymer processing, and specialized chemical synthesis.

Application

• Lubricant & Grease Additive: Functions as an extreme pressure (EP) and anti-wear agent, forming protective films on metal surfaces.
• Metal Extraction & Hydrometallurgy: Acts as a selective extractant for rare earth elements and transition metals in solvent extraction processes.
• Polymer & Resin Additive: Used as an internal lubricant and processing aid to improve flow and mold release in plastics.
• Emulsifier & Surfactant: Employed in the formulation of specialized emulsions for industrial and agrochemical applications.
• Corrosion Inhibitor: Provides protective properties in functional fluids and coatings for ferrous and non-ferrous metals.
• Chemical Intermediate: Serves as a key precursor in the synthesis of more complex phosphate esters and organophosphorus compounds.
