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.
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]
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.
CRC Industries is a manufacturer and distributor of industrial chemicals for maintenance and repair of marine, electrical, industrial, ... (2-26, 3-36, 5-56 + PTFE).
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]
1,2-Dibromoethane, also known as ethylene dibromide (EDB), is an organobromine compound with the chemical formula C 2 H 4 Br 2.Although trace amounts occur naturally in the ocean, where it is probably formed by algae and kelp, substantial amounts are produced industrially.

MDO is widely used by medium speed and medium/high speed marine diesel engines. It is also used in the larger low speed and medium speed propulsion engine which normally burn residual fuel. [1] Those fuels result from a catalytic cracking and visbreaking refinery. [1] Marine diesel oil has been condemned for its nimiety of sulfur, so many ...
