    Tributyl Phosphate (TBP) Chemical Properties and Reference Resources

    Information On Tributyl Phosphate From PubChem

    Tributyl phosphate is an odorless colorless to yellow liquid. Toxic by ingestion and inhalation. Tributyl phosphate is a trialkyl phosphate that is the tributyl ester of phosphoric acid. IDENTIFICATION: Tributyl phosphate is a colorless to pale yellow, odorless liquid. It is moderately soluble in water. USE: Tributyl phosphate is mainly used as a flame-retardant component of aircraft hydraulic fluid. It is used as a solvent for extracting rare earth elements, such as uranium and plutonium. Tributyl phosphate is also used in the making of plastics and in cement casings for oil wells. EXPOSURE: Exposure to tributyl phosphate can be from ingestion, inhalation, or skin or eye contact. This exposure will most often happen from occupational use of hydraulic fluid. If tributyl phosphate is released to the environment, it will bind tightly to dust particles in the air. Unbound tributyl phosphate will break down in air. It will move slowly through soil because it will bind with soil particles. It may volatilize slowly from moist soil and water surfaces. It may build up in aquatic organisms. It will be broken down in water by microbes. RISK: Studies of possible health effects in humans exposed to tributyl phosphate are not available. Damage to the urinary bladder was observed in laboratory rats exposed to very high concentrations of tributyl phosphate in their diet for up to 2 years. Some of the rats developed urinary bladder tumors. Tributyl phosphate was irritating when applied directly to the skin or eyes of laboratory animals. Other studies of laboratory animals given very high doses of tributyl phosphate by mouth found no clear evidence for abortions, birth defects, impaired reproductive performance, or severe neurological effects. ACGIH (2013) determined that tributyl phosphate is a Confirmed Animal Carcinogen with Unknown Relevance to Humans. The potential for tributyl phosphate to cause cancer in humans has not been assessed by the EPA IRIS program, the International Agency for Research on Cancer, or the U.S. National Toxicology Program 13th Report on Carcinogens.  Read more here.

    Tributyl Phosphate Solvent Extraction

    A 15–40% (usually about 30%) solution of tributyl phosphate in kerosene or dodecane is used in the liquid–liquid extraction (solvent extraction) of uranium, plutonium, and thorium from spent uranium nuclear fuel rods dissolved in nitric acid, as part of a nuclear reprocessing process known as PUREX.

    Scientific Overview Of Tributyl Phosphate

    Tributyl phosphate (TBP) is the most commonly used ligand in SNF reprocessing—as the extractant in the large-scale PUREX process and as a phase modifier in some other solvent extraction processes. Read more here.

    Tributyl Phosphate Industrial Uses

    The major uses of TBP in industry are as a component of aircraft hydraulic fluid, brake fluid, and as a solvent for extraction and purification of rare-earth metals from their ores. Read more here

    Tributyl phosphate (TBP) is a widespread extracting agent generally used in processing transuranium elements and removing them from wastewaters of the nuclear industry. Although the solubility of the ester in water is not very high, its loss, nevertheless, is significant because of the large scale of application. Read more here.

    Tributyl Phosphate In Kerosene

    A 15–40% (usually about 30%) solution of tributyl phosphate in kerosene or dodecane is used in the liquid–liquid extraction (solvent extraction) of uranium, plutonium, and thorium from spent uranium nuclear fuel rods dissolved in nitric acid, as part of a nuclear reprocessing process known as PUREX.

    Tributyl Phosphate Defoamer 

    Tributyl Phosphate (TBP) is a defoamer for concrete. Tributyl Phosphate (TBP) is used as a defoamer in the concrete, textile, and paper industries. Tributyl Phosphate is used as a defoamer additive in cement casings for oil wells.

    Information On Tributyl Phosphate From Wikipedia

    Tributyl phosphate, known commonly as TBP, is an organophosphorus compound with the chemical formula (CH3CH2CH2CH2O)3PO. This colorless, odorless liquid finds some applications as an extractant and a plasticizer. It is an ester of phosphoric acid with n-butanol. TBP is a solvent and plasticizer for cellulose esters such as nitrocellulose and cellulose acetate. It forms stable hydrophobic complexes with some metals; these complexes are soluble in organic solvents as well as supercritical CO2. The major uses of TBP in industry are as a component of aircraft hydraulic fluid, brake fluid, and as a solvent for extraction and purification of rare-earth metals from their ores. TBP finds its use as a solvent in inks, synthetic resins, gums, adhesives (namely for veneer plywood), and herbicide and fungicide concentrates. As it has no odour, it is used as an anti-foaming agent in detergent solutions, and in various emulsions, paints, and adhesives. It is also found as a de-foamer in ethylene glycol-borax antifreeze solutions.[citation needed] In oil-based lubricants addition of TBP increases the oil film strength. It is used also in mercerizing liquids, where it improves their wetting properties. It can be used as a heat-exchange medium. TBP is used in some consumer products such as herbicides and water-thinned paints and tinting bases. A 15–40% (usually about 30%) solution of tributyl phosphate in kerosene or dodecane is used in the liquid–liquid extraction (solvent extraction) of uranium, plutonium, and thorium from spent uranium nuclear fuel rods dissolved in nitric acid, as part of a nuclear reprocessing process known as PUREX. The shipment of 20 tons of tributyl phosphate to North Korea from China in 2002, coinciding with the resumption of activity at Yongbyon Nuclear Scientific Research Center, was seen by the United States and the International Atomic Energy Agency as cause for concern; that amount was considered sufficient to extract enough material for perhaps three to five potential nuclear weapons.
