1,1,2,2-Tetrabromoethane, or simply tetrabromoethane (TBE), is a halogenated hydrocarbon, chemical formula C 2 H 2 Br 4.Although three bromine atoms may bind to one of the carbon atoms creating 1,1,1,2-tetrabromoethane this is not thermodynamically favorable, so in practice tetrabromoethane is equal to 1,1,2,2-tetrabromoethane, where each carbon atom binds two bromine atoms.
Oil mist technology is mature and has been in highly successful plant-wide use since the early 1960s. [1] [2] There are also plant-wide oil distribution systems whereby liquid oil (not an oil/air mixture) is pressurized and injected, through spray nozzles, into the pump bearings. These oil spray systems are not to be confused with the more ...
Tetrabromoethylene is a potential fungicide and bactericide on fruits. [1] It was used in mineral separation. [2] It is prepared from acetylene and bromine in multiple steps. [1] [3] One method involves dehydrobromination of pentabromoethane, other method involves bromination of dibromoethylene in chloroform. [1]
Tribromoethylene is a bromoalkene and a trihaloethylene with the chemical formula C 2 HBr 3.It can be made from 1,1,2,2-tetrabromoethane. [3]Tribromoethylene reacts with potassium hydroxide to yield dibromoacetylene via dehydrobromination, [4] this reaction is analogous to the synthesis of dichloroacetylene from trichloroethylene.
These toxic chemicals are avoided today in consideration of the fact that there are alternative water based, non-toxic heavy liquids like sodium polytungstate solutions. [1] With this relatively new heavy liquid densities up to 3.1 g·cm −3 can be adjusted . Adding parts of pulverulent tungsten carbide increases the density to 4.6 g·cm −3. [2]
