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.
Dibromodifluoromethane is a mixed halomethane. It is a colorless non-flammable liquid. Along with Halons 1211, 2402, and 1301, it is one of the most effective fire extinguishers, however, it is also very toxic. It is a class I ozone depleting substance (ODS).
Halon 1211 is also a potent greenhouse gas with a 100-year global warming potential 2,070 times that of carbon dioxide and an atmospheric lifetime of 16.0 years. [6] Recycling of Halon 1211 allows it to remain in use, [7] [8] although parts availability is limited to a few manufacturers and can be an issue. Halon 1211 is still widely used in ...
Halon systems are among the most effective and commonly used fire protection systems used on commercial aircraft. Halon 1301 is the primary agent used in commercial aviation engine, cargo compartments, and auxiliary power unit fire zones. [9] [10] Efforts to find a suitable replacement for Halon 1301 have not produced a widely accepted replacement.
However, Halon 1301 fire suppression is not completely non-toxic; very high temperature flame, or contact with red-hot metal, can cause decomposition of Halon 1301 to toxic byproducts. The presence of such byproducts is readily detected because they include hydrobromic acid and hydrofluoric acid , which are intensely irritating.
Nike posted net income of $1.05 billion, or 70 cents per share, in the quarter that ended Aug. 31. That compares with $1.45 billion, or 94 cents per share, in the year-ago period. Sales fell 10% ...
Bromochloromethane or methylene bromochloride and Halon 1011 is a mixed halomethane. It is a heavy low-viscosity liquid with refractive index 1.4808. Halon 1011 was invented for use in fire extinguishers in Germany during the mid-1940s, in an attempt to create a less toxic, more effective alternative to carbon tetrachloride .
Tribromofluoromethane [1] or Halon 1103 or R 11B3 is a fully halogenated mixed halomethane or, more exactly, a bromofluorocarbon (BFC). It is a colorless to yellow liquid. It is a colorless to yellow liquid.
