Product Description:
2-Ethylhexyl phosphoric acid, mono(2-ethylhexyl) ester, commonly known as P507, is an organophosphorus compound primarily used as a highly effective and selective extractant in solvent extraction processes. It is a clear, colorless to pale yellow viscous liquid, practically insoluble in water but soluble in most organic solvents.
P507 belongs to the class of acid extractants, specifically a monoalkyl phosphoric acid, and is particularly noted for its strong extracting capability for various metal ions, especially rare earth elements, cobalt, nickel, and other non-ferrous metals from aqueous solutions.
Its chemical structure with two 2-ethylhexyl groups provides excellent hydrophobicity and stability in acidic conditions, making it suitable for industrial hydrometallurgical applications.
Key Applications:
-
Rare Earth Element Extraction:?Widely used in the separation and purification of rare earth elements (REEs) from their ores or mixed solutions, providing high selectivity and efficiency.
-
Cobalt and Nickel Separation:?Essential in the hydrometallurgical recovery and separation of cobalt and nickel, particularly from leach solutions of spent batteries, laterite ores, and other industrial wastes.
-
Non-Ferrous Metal Extraction:?Employed in the extraction of other non-ferrous metals like zinc, copper, and uranium from acidic solutions.
-
Hydrometallurgy:?A core reagent in solvent extraction circuits for the recovery and refining of various metals in the mining and recycling industries.
-
Analytical Chemistry:?Used in laboratory settings for the analytical separation and preconcentration of metal ions.
Packaging and Shipping?
Available in plastic drums (e.g., 200 kg or 1000 kg IBC tanks) or bulk containers, suitable for industrial scale applications.
