Description

Sodium Dipentyl Phosphate is an organophosphorus compound widely utilized as an effective extractant and phase transfer catalyst. This chemical is valued for its ability to selectively separate and concentrate metal ions, particularly rare earth elements, in complex industrial matrices. It serves as a critical reagent for companies in the hydrometallurgy, nuclear fuel reprocessing, and specialty chemical synthesis sectors, where precise separation processes are paramount.

Application

• As a key solvent extractant for the separation and purification of rare earth elements (e.g., lanthanum, cerium, neodymium).
• Used in hydrometallurgical processes for the recovery of valuable metals from ores and secondary sources.
• Employed as a phase transfer catalyst (PTC) in organic synthesis to facilitate reactions between reagents in immiscible phases.
• Acts as a surfactant intermediate and corrosion inhibitor in specialized formulations.
• Applied in nuclear fuel cycle operations for the selective extraction of specific actinides.
• Serves as a chelating agent in analytical chemistry for the pre-concentration of trace metals.
• Utilized in the formulation of specialty lubricant additives and flame retardants.
• Functions as an emulsifier and stabilizer in certain polymerization processes.

Quality Control

Our Sodium Dipentyl Phosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, ionic content, and performance as an extractant. A comprehensive Certificate of Analysis (COA) detailing assay, moisture content, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance. Keep away from strong oxidizing agents.
