Description

Diethyl Hexyl Phosphate is an organophosphorus compound widely utilized as an effective extractant and surfactant. Its unique chemical structure provides excellent solvating properties for metal ions, making it a critical component in hydrometallurgical processes. This product is essential for industries involved in rare earth separation, metal recovery, and the formulation of specialized lubricant additives and corrosion inhibitors.

Application

• Solvent Extraction in Hydrometallurgy: A key extractant for the separation and purification of rare earth elements (e.g., lanthanides), cobalt, nickel, and other valuable metals from aqueous solutions.
• Metal Recovery & Recycling: Used in processes to recover precious and base metals from electronic waste, spent catalysts, and industrial effluents.
• Lubricant & Fuel Additive: Acts as an anti-wear agent, friction modifier, and corrosion inhibitor in synthetic lubricants and industrial oils.
• Surfactant & Emulsifier: Serves as a specialty surfactant in pesticide formulations, textile processing aids, and emulsion polymerization.
• Chemical Intermediate: Employed in the synthesis of other organophosphate esters and flame retardants.
• Analytical Chemistry: Used as a chelating agent in specific analytical techniques for metal ion detection and separation.
