Description

Bis(2-Ethylhexyl) Phosphate is a versatile organophosphorus compound widely used as an extractant and acid catalyst. Its primary commercial value lies in its strong chelating properties and solubility in organic media, making it essential for metal separation and purification processes. This product is critical for industries involved in hydrometallurgy, rare earth element processing, and the formulation of specialized lubricant additives and plasticizers.

Application

• Solvent Extraction Agent: A key extractant for the separation and recovery of valuable metals such as uranium, vanadium, cobalt, nickel, and rare earth elements from aqueous solutions in hydrometallurgical processes.
• Catalyst & Intermediate: Serves as an acid catalyst in organic synthesis and as a chemical intermediate for producing other phosphate esters and surfactants.
• Lubricant & Fuel Additive: Used as an anti-wear and extreme pressure additive in synthetic lubricants and as a detergent additive in fuels.
• Plasticizer & Stabilizer: Functions as a secondary plasticizer and stabilizer in PVC and other polymer formulations.
• Analytical Chemistry: Employed in analytical techniques for the selective extraction and preconcentration of metal ions prior to analysis.
• Corrosion Inhibitor: Formulated into corrosion inhibitor packages for industrial cooling water systems and metal treatment fluids.
