Tri-n-butyl phosphate is primarily used as an extraction solvent in the PUREX (Plutonium Uranium Recovery by EXtraction) process for nuclear fuel reprocessing, where it plays a crucial role in the separation of plutonium and uranium from fission products. Beyond its nuclear applications, TBP is also employed as a plasticizer in the production of plastics and resins, enhancing flexibility and durability. Additionally, it is utilized in the formulation of hydraulic fluids, lubricants, and as a reagent in various chemical syntheses. Its ability to dissolve a wide range of organic compounds makes it valuable in laboratory settings for solvent extraction and chromatography.
