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 .
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. It reacts slowly with atmospheric oxygen, and rapidly with other oxidizing agents, to give tributylphosphine oxide.
Dodecane (also known as dihexyl, bihexyl, adakane 12, or duodecane) is an oily liquid n-alkane hydrocarbon with the chemical formula C 12 H 26 (which has 355 isomers). It is used as a solvent, distillation chaser, and scintillator component. It is used as a diluent for tributyl phosphate (TBP) in nuclear reprocessing plants. [4]
The phosphate ion has a molar mass of 94.97 g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion H(PO
Phosphoric acids produced from phosphate rock or thermal processes often requires purification. A common purification methods is liquid-liquid extraction, which involves the separation of phosphoric acids from water and other impurities using organic solvents, such as tributyl phosphate (TBP), methyl isobutyl ketone (MIBK), or n-octanol ...
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 ...
The uranyl ion is an oxycation of uranium in the oxidation state +6, with the chemical formula UO 2+ 2. It has a linear structure with short U–O bonds, indicative of the presence of multiple bonds between uranium and oxygen. Four or more ligands may be bound to the uranyl ion in an equatorial plane around the uranium atom.
