An accidental release of phosgene gas at a DuPont facility in West Virginia killed one employee in 2010. [41] The US Chemical Safety Board released a video detailing the accident. [42] Six years later, a phosgene leak occurred in a BASF plant in South Korea, where a contractor inhaled a lethal dose of phosgene. [43]
Liquefied chlorine is transported for eventual solution in water, after which it is used for water purification, sanitation of industrial waste, sewage and swimming pools, bleaching of pulp and textiles and manufacture of carbon tetrachloride, glycol and numerous other organic compounds as well as phosgene gas.
Diphosgene converts to phosgene upon heating or upon catalysis with charcoal. It is thus useful for reactions traditionally relying on phosgene. For example, it convert amines into isocyanates, secondary amines into carbamoyl chlorides, carboxylic acids into acid chlorides, and formamides into isocyanides. Diphosgene serves as a source of two ...
The oil and gas industry is seen as distinct. So, whilst it is true that natural gas is a "gas" used in "industry" - often as a fuel, sometimes as a feedstock, and in this generic sense is an "industrial gas"; this term is not generally used by industrial enterprises for hydrocarbons produced by the petroleum industry directly from natural ...
Owing to the hazardous nature of phosgene, the production of isocyanates requires special precautions. [1] A laboratory-safe variation masks the phosgene as oxalyl chloride . [ 5 ] Also, oxalyl chloride can be used to form acyl isocyanates from primary amides , which phosgene typically dehydrates to nitriles instead.
Traces of a toxic, colorless gas were found at the headquarters of Sweden’s security agency where a suspected gas leak last week forced authorities to evacuate some 500 people from the facility ...
Many intelligent nonchemists are under the impression that phosgene's lethality arises from the release of HCl due to its hydrolysis. But an authoritative text and the chemistry described in the article explain that the mechanism is otherwise. Phosgene preferentially reacts with amino groups, it does not hydrolyze (as you seem to understand).
In this case, sodium was able to react with water to release hydrogen gas and large amounts of heat, which has the potential to explode. The Charlotte Fire Department developed training to respond to fires involving hazardous materials, ensured that protective clothing was available to those responding, and expanded the fire prevention ...
