Bis(2,4,4-Trimethylpentyl)-Phosphinic Acid Cyanex 272 CAS 83411-71-6

BLIT Chemical Bis(2,4,4-Trimethylpentyl)-Phosphinic Acid is a high-purity organophosphorus compound widely used in hydrometallurgical applications, particularly in solvent extraction processes. It offers excellent selectivity for extracting and separating rare earth and transition metals from aqueous solutions.

Specification:

Application:

Bis(2,4,4-Trimethylpentyl)-Phosphinic Acid Cyanex 272 is a new type of acidic phosphorus extractant with high selectivity for separation of cobalt and nickel in sulfate and chloride media. It is also suitable for the extraction and separation of rare earth, gallium (Ga), indium (In), molybdenum (Mo), germanium (Ge), zirconium (Zr) and other metals.

Solvent Extraction:Extraction and separation of rare earth elements (REEs) and base metals like cobalt, nickel, and zinc.

Hydrometallurgy:Used in mining and refining operations for efficient metal recovery.

Industrial Processing:Acts as a metal-binding agent in purification systems.

Usage Guidelines:

Concentration:Typically used in concentrations of 0.1% to 5% depending on the metal to be extracted and the process requirements.

Handling:Wear appropriate personal protective equipment (PPE), including gloves and goggles, when handling the product to avoid skin and eye contact.

Application Method:Bis(2,4,4-Trimethylpentyl)-Phosphinic Acid is usually diluted with an appropriate organic solvent for use in solvent extraction systems. Follow the specific formulation guidelines for different metal separation processes.The diluent generally used in nickel-cobalt separation is sulfonated kerosene.

Compatibility:It is compatible with a wide range of organic solvents such as kerosene, diesel, and aromatic hydrocarbons. Ensure proper testing of solvent combinations before full-scale application.
