Bromotrifluoromethane, commonly referred to by the code numbers Halon 1301, R13B1, Halon 13B1 or BTM, is an organic halide with the chemical formula C Br F 3. It is used for gaseous fire suppression as a far less toxic alternative to bromochloromethane .
The brand name "Halon" is frequently used interchangeably for BFCs. owever, not all Halons are technically BFCs (some contain chlorine also). BFCs attack the ozone layer even more aggressively than chlorofluorocarbons (CFCs), [ 2 ] and are powerful greenhouse gases , although due to shorter atmospheric lifetimes not as powerful as equivalent ...
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
Cuts in funding for the Internal Revenue Service, long eyed by Republicans in Congress, would increase the federal deficit by $140 billion over a decade, slow service and reduce complex audits of ...
This OH − is a nucleophile with a clearly negative charge, as it has excess electrons it donates them to the carbon, which results in a covalent bond between the two. Thus C–X is broken by heterolytic fission resulting in a halide ion, X −. As can be seen, the OH is now attached to the alkyl group, creating an alcohol.
Bird flu has been on the rise in Washington state and one sanctuary was hit hard: 20 big cats – more than half of the facility’s population – died over the course of weeks.
Ohio turned into winter wonderland over the weekend as lake-effect snow buried northern parts of the state and brought with it below-freezing temperatures.. Drone footage captured by Kelly Matter ...
Bromomethane was once used in specialty fire extinguishers, prior to the advent of less toxic halons, as it is electrically non-conductive and leaves no residue. It was used primarily for electrical substations, military aircraft, and other industrial hazards. It was never as popular as other agents due to its high cost and toxicity.
