Bis(2-ethylhexyl)phosphate is primarily used as an extractant in hydrometallurgical processes for the separation and purification of metals. It is particularly effective in solvent extraction techniques for recovering valuable metals such as uranium, vanadium, and rare earth elements from ores and industrial waste streams. Its ability to selectively bind with metal ions makes it a key component in the production of high-purity metals for use in electronics, energy storage, and nuclear industries. Additionally, it serves as a plasticizer and stabilizer in certain polymer formulations, enhancing flexibility and durability in materials like PVC. Its role in corrosion inhibition for industrial equipment is also noteworthy, where it helps protect metal surfaces from degradation in harsh environments.
