Tetrabromoethane - Wikipedia

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. Uses. The compound has no commercial use. It

LST Heavy liquid for density separations - Chem

The organic heavy liquids form the "older" generation of heavy liquids. Two of the organic heavy liquids most commonly in use are bromoform and tetrabromoethane (TBE). Of these, bromoform has the lower viscosity (1.8 cP) but is considered more hazardous to work with because it has the higher vapour pressure (5.9 mm Hg at 25 o C).

Heavy Media Separation - an overview ScienceDirect

A mechanised method for this process is separation using heavy media plants where the metal is segregated based on its density. The mixed solids are placed in a liquid denser than one metal and less dense than the others. The denser material sinks whilst the less dense floats. Eddy current separation is used for separation of plastic and paper from UBCs emanating from kerbside collection of ...
