Tributyl phosphate (TBP) is a trialkyl phosphate that is the tributyl ester of phosphoric acid. TBP is a toxic organophosphorous compound widely used in many industrial applications, including significant usage in nuclear processing. TBP is a solvent and plasticizer for cellulose esters such as nitrocellulose and cellulose acetate. The major uses of TBP in industry are as a component of aircraft hydraulic fluid and as a solvent for extraction and purification of rare earth metals from their ores, such as uranium and plutonium. TBP is used also in mercerizing liquids, where it improves their wetting properties. TBP is also used as a heat exchange medium. TBP is used in some consumer products such as herbicides and water thinned paints and tinting bases.
Tributyl phosphateis an odorless colorless to yellow liquid. The solubility of TBP is only 280 mg/L in water at 25°C. It is soluble in diethyl ether, benzene, carbon disulfide. It can be miscible with ethanol. It is stable, but it is incompatible with strong oxidizing agents.
