1,2-Dibromotetrafluoroethane (C 2 Br 2 F 4) is a haloalkane. It is also known under codenames R-114B2 and Halon 2402. It is a colorless liquid with a boiling point of 47.2 °C. R-114B2 is occasionally used in fire suppression systems. It is highly volatile, passes through soil to air, and can be detected in the parts-per-quadrillion range.
1,1,2,2-Tetrafluoroethane (also called R-134 or HFC-134) is a hydrofluorocarbon, a fluorinated alkane. It is an isomer of the more-used 1,1,1,2-tetrafluoroethane (R-134a). It is used as a foam expansion agent and heat transfer fluid.
1,2-Dibromoethane, also known as ethylene dibromide (EDB), is an organobromine compound with the chemical formula C2H4Br2. Although trace amounts occur naturally in the ocean, where it is probably formed by algae and kelp, substantial amounts are produced industrially.
1,2-Dibromotetrachloroethane (DBTCE) is an organohalide with the chemical formula C2Br2Cl4. It is a crystalline solid that emits lachrymatory (tear -producing) vapours. [2] Dibromotetrachloroethane can be used as a fungicide, [2] flame retardant [3] and a source for bromine in the laboratory. [4] Because the 1,1-dibromotetrachloroethane isomer ...

Uses. 1,1,1,2-Tetrafluoroethane is a non-flammable gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. These devices began using 1,1,1,2-tetrafluoroethane in the early 1990s as a replacement for the more environmentally harmful R-12. Retrofit kits are available to convert units that ...
1,2-Difluoroethane is a saturated hydrofluorocarbon containing an atom of fluorine attached to each of two carbons atoms. The formula can be written CH 2 FCH 2 F. It is an isomer of 1,1-difluoroethane. It has a HFC name of HFC-152 with no letter suffix. [3] When cooled to cryogenic temperatures it can have different conformers, gauche and trans ...
