Description

Bis[p-(1,1,3,3-Tetramethylbutyl)Phenyl] Hydrogen Phosphate is a high-purity organophosphorus compound valued for its role as an effective extractant and phase transfer catalyst. Its unique branched alkylphenol structure provides excellent selectivity and stability in complex chemical separations. This product is essential for manufacturers and researchers in the metallurgical, fine chemical, and pharmaceutical industries seeking reliable performance in liquid-liquid extraction processes.

Application

• Solvent Extraction Agent: Primary use in the selective extraction and purification of rare earth elements, precious metals (e.g., gold, platinum), and transition metals from aqueous solutions.
• Phase Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly useful in organic synthesis for alkylation and esterification reactions.
• Acidic Extractant in Hydrometallurgy: Employed in the recovery and separation of metal ions from leach solutions in mining and metal refining operations.
• Additive for Lubricants and Fuels: Acts as an anti-wear and extreme pressure additive, enhancing the performance of industrial lubricants and functional fluids.
• Intermediate for Surfactants: Serves as a key building block in the synthesis of specialized phosphate ester surfactants for industrial and agrochemical formulations.
• Plasticizer and Stabilizer Precursor: Used in the production of specialty plasticizers and stabilizers for polymers requiring enhanced properties.

Quality Control

Our Bis[p-(1,1,3,3-Tetramethylbutyl)Phenyl] Hydrogen Phosphate is manufactured under a strict quality management system. Each batch is analyzed to ensure it meets precise specifications for purity, acidity, and identity. A comprehensive Certificate of Analysis (COA) documenting results for assay, water content, and specific impurities is provided with every shipment to guarantee consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed tightly after use to prevent absorption of atmospheric moisture. Keep away from strong bases and incompatible materials.
