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]
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 ...
It behaves like phosgene, to which it cracks thermally: OC(OCCl 3) 2 ⇌ 3 OCCl 2. Alcohols are converted to carbonates. Primary and secondary amines are converted to ureas and isocyanates. [6] [7] [9] [10] Triphosgene has been used to synthesize chlorides. [8] Some Alkyl chlorides are prepared by treating alcohols with a mixture of triphosgene ...
Phosgene (CG) Disulfur decafluoride; Perfluoroisobutene; Acrolein; Diphenylcyanoarsine; Phosgene is the most dangerous commonly used pulmonary agent (although disulfur decafluoride and perfluoroisobutene are both even more dangerous, with respectively 4 and 10 times the lethality of phosgene, neither is widely used). It is a colorless gas under ...
Additionally, chemical burns can be caused by biological toxins (such as anthrax toxin) and by some types of cytotoxic chemical weapons, e.g., vesicants such as mustard gas and Lewisite, or urticants such as phosgene oxime. Chemical burns may: need no source of heat; occur immediately on contact; not be immediately evident or noticeable; be ...
The German phosgene attack of 19 December 1915 was the first use of phosgene gas against British troops by the German army. The gas attack took place at Wieltje , north-east of Ypres in Belgian Flanders on the Western Front in the First World War .
In October 2013, he advised the mother of Jesse Brown, a 29-year-old Idaho addict who, as a precondition of his early release from prison, was compelled to enter a psychologically brutal “therapeutic community” behind bars. Years earlier, Brown had suffered a traumatic brain injury in a car accident.
Chloroform: Chloroform is stabilized with small quantities of amylene or ethanol, because exposure of pure chloroform to oxygen and ultraviolet light produces phosgene gas. Some chloroform solutions come as pre-made a 96% chloroform, 4% isoamyl alcohol mixture that can be mixed with an equal volume of phenol to obtain the 25:24:1 solution.
