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 .
Di(2-ethylhexyl)phosphoric acid (DEHPA or HDEHP) is an organophosphorus compound with the formula (C 8 H 17 O) 2 PO 2 H. The colorless liquid is a diester of phosphoric acid and 2-ethylhexanol . It is used in the solvent extraction of uranium , vanadium and the rare-earth metals .
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]
In recent years, n-dodecane has garnered attention as a possible surrogate for kerosene-based fuels such as Jet-A, S-8, and other conventional aviation fuels. It is considered a second-generation fuel surrogate designed to emulate the laminar flame speed, largely supplanting n-decane, primarily due to its higher molecular mass and lower hydrogen-to-carbon ratio which better reflect the n ...
TBT, or tributyltin, tributylstannyl or tributyl stannic hydride compounds are organotin compounds. They have three butyl groups covalently bonded to a tin(IV) atom. [5] A general formula for these compounds is (CH 3 CH 2 CH 2 CH 2) 3 Sn−X. The −X is typically a chloride −Cl, hydroxide −OH, or a carboxylate RCO 2 −, where R is an ...
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 ...
As such, it is a potential replacement of DEHP and DINP. [1] It is a colorless liquid that is soluble in organic solvents. It is found in nail polish and other cosmetics. It is prepared by acetylation of tributylcitrate. [2]
