Phosgene is an organic chemical compound with the formula COCl 2. It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut ...
Phosgene oxime, or CX, is an organic compound with the formula Cl 2 C=N−O H. It is a potent chemical weapon , specifically a nettle agent . The compound itself is a colorless solid, but impure samples are often yellowish liquids.
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 ...
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 ...

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 ...
Toxic gases, by contrast, cause death by other mechanisms, such as competing with oxygen on the cellular level (e.g. carbon monoxide) or directly damaging the respiratory system (e.g. phosgene). Far smaller quantities of these are deadly. Notable examples of asphyxiant gases are methane, [1] nitrogen, argon, helium, butane and propane.
John Davy FRS FRSE (24 May 1790 – 24 January 1868) was a Cornish doctor, amateur chemist, brother of the noted chemist Sir Humphry Davy, and cousin of Edmund Davy.. During his career, Davy discovered phosgene, silicon tetrafluoride, and concluded that chlorine was an element.
