TBP is a solvent and plasticizer for cellulose esters such as nitrocellulose and cellulose acetate, similarly to tricresyl phosphate. It is also used as a flame retardant for cellulose fabrics such as cotton. [7] [8] It forms stable hydrophobic complexes with some metals; these complexes are soluble in organic solvents as well as supercritical ...
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]
To be confirmed (TBC), to be resolved (TBR), [1] or to be provided (TBP) [2] – details may have been determined and possibly announced, but are still subject to change prior to being finalized. To be arranged , to be agreed ( TBA ), to be determined ( TBD ) or to be decided [ 3 ] – the appropriateness, feasibility, location, etc. of a given ...
The reaction can be used for the synthesis of 2,6-di-tert-butyl-4-methoxyphenol, which is frequently used as an antioxidant. Synthese von 2,6-Di- tert -butyl-4-methoxyphenol aus 2,4,6-TTBP 2,4,6-TTBP is used as stabilizers , free-radical scavengers and antioxidants in technical applications, such as in fuels , hydraulic fluids and lubricating ...
Red oil is defined as a substance of varying composition formed when an organic solution, typically tri-n-butyl phosphate (TBP, an agent used for extracting heavy metals in nuclear reprocessing plants) and its diluent, comes in contact with concentrated nitric acid at a temperature above 120 °C.
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.
TbP can be obtained by the reaction of terbium and red phosphorus at 800–1000 °C: 4 Tb + P 4 → 4 TbP. ... The compound is a semiconductor used in high power, ...
Ke – Is used as an abbreviation for Cost of Equity (COE). Ke is the risk-adjusted, theoretical rate of return on a Company's invested excess capital obtained through external investment s. Among other things, the value of Ke and the Cost of Debt (COD) [ 6 ] enables management to arbitrate different forms of short and long term financing for ...
