Tributyl phosphate, known commonly as TBP, is an organophosphorus compound with the chemical formula (CH 3 CH 2 CH 2 CH 2 O) 3 PO. This colourless, odorless liquid finds some applications as an extractant and a plasticizer .
Due to its properties (including that it is a mild biocide), tris(2-ethylhexyl)phosphate is used in a variety of applications: as a plasticizer in polymers (PVC, PU, NBR and others) giving good cold flexibility and flame retarding properties; as a carrier for pigments and dyes used in colouring polymers; as a component in cutting fluid [5]
Tributyl phosphate is often used, as well as dibutyl-, diamyl-, and dihexylphosphonates. The synergistic effects are thought to occur by the addition of the trialkylphosphate to the uranyl-DEHPA complex by hydrogen bonding.
Tributylphosphine is the organophosphorus compound with the chemical formula P(CH 2 CH 2 CH 2 CH 3) 3, often abbreviated as PBu 3.It is a tertiary phosphine.It is an oily liquid at room temperature, with a nauseating odor.
Tricresyl phosphate (TCP), is a mixture of three isomeric organophosphate compounds most notably used as a flame retardant. [1] Other uses include as a plasticizer in manufacturing for lacquers and varnishes and vinyl plastics and as an antiwear additive in lubricants. Pure tricresyl phosphate is a colourless, viscous liquid, although ...
Triphenyl phosphate (TPhP) is the chemical compound with the formula OP(OC 6 H 5) 3. It is the simplest aromatic organophosphate . This colourless solid is the ester (triester) of phosphoric acid and phenol .
Lanxess AG is a German specialty chemicals company based in Cologne, Germany that was founded in 2004, via the spin-off of the chemicals division and parts of the polymers business from Bayer AG. [ 2 ]
The organic solvent consists of 30% tributyl phosphate (TBP) in a hydrocarbon such as kerosene. Uranyl(VI) UO 2+ 2 ions are extracted in the organic phase as UO 2 (NO 3) 2 ·2TBP complexes; plutonium is extracted as similar complexes. The heavier actinides, primarily americium and curium, and the fission products remain in the aqueous phase ...
