- 1,1,2,2-Tetrabromoethane
1,1,2,2-Tetrabromoethane (TBE) is a
halogenated hydrocarbon , chemical formula C2H2Br4. It has an unusually highdensity for an organic compound, near 3 g/mL, due largely to the fourbromine atoms. TBE is aliquid atroom temperature , and is used to separatemineral ores from its supporting rock by means of preferential flotation. Sand,limestone ,dolomite , and other types of rock material will float on TBE, while minerals such assphalerite ,galena andpyrite will sink. A related compound,bromoform , is also sometimes used in these applications, however, TBE is more practical because of its wider liquid range, and lower vapor pressure. Acute TBE poisoning has been known to occur.References
