Description

2-Ethylhexylphosphoric Acid Oleylamine Salt is a specialized organophosphorus compound widely used as an effective extractant and phase transfer catalyst. Its value lies in its unique ability to selectively complex with and transport specific metal ions across organic-aqueous interfaces. This makes it a critical material for industries requiring high-purity metal separation and recovery, such as hydrometallurgy for rare earth elements, battery material processing, and the purification of industrial catalysts.

Application

• Rare Earth Element (REE) Separation: A key extractant in solvent extraction circuits for separating and purifying lanthanides like neodymium, dysprosium, and praseodymium.
• Battery Metal Recovery: Used in the extraction and purification of cobalt, nickel, and lithium from primary ores and recycled battery black mass.
• Catalyst Manufacturing: Employed in the synthesis and purification of homogeneous catalysts, particularly those involving precious and transition metals.
• Hydrometallurgical Processing: Facilitates the selective recovery of valuable metals like copper, zinc, and vanadium from complex leach solutions.
• Wastewater Treatment: Applied in advanced treatment systems for the selective removal and recovery of heavy metal contaminants.
• Analytical Chemistry: Serves as a chelating agent in sample preparation and pre-concentration steps for trace metal analysis.
