Description:
Tributyl Phosphate (abbreviated as TBP) is a commonly used extractant. This product appears as a colorless to light yellow transparent liquid at room temperature, with moderate viscosity and good thermal stability. The phosphorus-oxygen double bond in its molecular structure gives it excellent coordination capability and solvent properties, making it widely applicable in various fields including hydrometallurgy and nuclear fuel processing.

Performance and Applications:
1. TBP demonstrates excellent extraction selectivity and high distribution coefficients for various metal ions, particularly suitable for the separation and purification of rare metals such as uranium, thorium, zirconium, hafnium, and rare earth elements. Its molecules can form stable complexes with metal ions through coordination bonds, enabling efficient liquid-liquid extraction, and plays a crucial role in nuclear waste treatment and rare earth smelting.
2. In organic synthesis and industrial wastewater treatment, TBP can be used as an effective defoamer and solvent. Its unique characteristics allow it to remain stable under high temperatures and in acidic/alkaline environments, making it suitable for production of concrete additives, surface treatment agents, and dye intermediates.
3. TBP exhibits good mutual solubility with most organic solvents such as kerosene, xylene, and chloroform. It can be used as a synergistic extractant or modifier to enhance phase separation speed and separation efficiency in extraction systems, while also serving as a cosolvent and plasticizer in pesticide formulations and coating industries.
Advantages:
1. Broad applicability and excellent chemical stability, maintaining high activity even in strong acid, strong alkali, and high temperature environments.
2. High extraction selectivity, particularly suitable for extraction and separation of rare metals from complex components, with strong process compatibility.
