TBP shows high selectivity in extracting various metal ions with favorable distribution coefficients, particularly effective for separating and purifying rare metals including uranium, thorium, zirconium, hafnium, and rare earth elements. It forms stable coordination complexes with metal ions, enabling efficient liquid-liquid extraction processes crucial in nuclear waste management and rare earth refining.
In organic synthesis and industrial wastewater treatment, TBP serves as an effective foam suppressor and solubilizer. It maintains stability under elevated temperatures and acidic/alkaline conditions, making it suitable for producing concrete additives, surface treatment agents, and dye intermediates.
TBP demonstrates good miscibility with common organic diluents like kerosene, xylene, and chloroform. It can function as a synergistic extractant or process modifier to improve phase separation efficiency, while also acting as plasticizer and co-solvent in pesticide formulations and coating applications.
Broad applicability and strong chemical resistance, maintaining reactivity under aggressive acidic, alkaline, and high-temperature conditions.
High extraction selectivity, especially suitable for recovering rare metals from complex mixtures, with excellent process compatibility.
