Tributyl phosphate CAS #126-73-8

Tributyl phosphate (126-73-8);is 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.
Tributyl phosphate
Tributyl phosphate (TBP) is an organophosphorus compound widely used as a solvent in nuclear fuel reprocessing for the extraction of uranium and plutonium from other radionuclides.
The major uses of tributyl phosphate (TBP) in industry are as a flame retardant component of aircraft hydraulic fluid and as a solvent for rare earth extraction and purification. Minor uses of TBP include use as a defoamer additive in cement casings for oil wells, as an anti-air entrainment additive for coatings and floor finishes, as a solvent in nuclear fuel processing, and as a carrier for fluorescent dyes.
The microbial degradation of tributyl phosphate was carried out using Klebsiella pneumoniae S3 isolated from the soil. The solubilization behavior of TBP in aqueous solutions of L64-Pluronics was studied using light and small angle neutron scattering (SANS).
