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 .
Although natural TBP has been identified in ocean sediments as a metabolite of marine fauna, [5] the commercial product is prepared industrially. In 2001, the production volume of TBP was estimated to be 2500 tonnes/year in Japan and 9500 tonnes/year worldwide. [2] TBP can be prepared by the controlled reaction of elemental bromine with phenol: [3]
Names of many computer terms, especially computer applications, often relate to the function they perform, e.g., a compiler is an application that compiles (programming language source code into the computer's machine language). However, there are other terms with less obvious origins, which are of etymological interest.

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.
The quantity used for the curing of UP resins is about 1-2%. [ 2 ] A disadvantage, particularly in the production of polymers for applications in the food or cosmetics sector, is the possible formation of benzene as a decomposition product which can diffuse out of the polymer (for example, an LDPE packaging film).
For this reason di-tert-butyl peroxide is commonly used as a radical initiator in organic synthesis and polymer chemistry. The decomposition reaction proceeds via the generation of methyl radicals. (CH 3) 3 COOC(CH 3) 3 → 2 (CH 3) 3 CO • (CH 3) 3 CO • → (CH 3) 2 CO + CH • 3 2 CH • 3 → C 2 H 6
