Bis(2-ethylhexyl)phosphate is widely used as a solvent extraction agent in the separation and purification of metals, particularly in the mining and metallurgical industries. It is effective in extracting rare earth elements, uranium, and other valuable metals from ores and industrial waste. Additionally, it serves as a plasticizer in the production of polymers, enhancing flexibility and durability in materials like PVC. In the field of analytical chemistry, it is utilized as a reagent for selective ion extraction and separation processes. Its properties also make it suitable for use in lubricant formulations, where it improves performance under high-pressure conditions.
