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 hay or grass. [ 7 ] It can be thought of chemically as the double acyl chloride analog of carbonic acid , or structurally as formaldehyde with the hydrogen atoms replaced by chlorine ...
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.
Examples of these substances are phosgene, which has been used as a chemical weapon but which is also a precursor in the manufacture of many legitimate organic compounds, and triethanolamine, used in the manufacture of nitrogen mustard but also commonly used in toiletries and detergents.
Toxic: a chemical that has a median lethal concentration (LC 50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats ...
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 ...
Triphosgene (bis(trichloromethyl) carbonate (BTC)) is a chemical compound with the formula OC(OCCl 3) 2. It is used as a solid substitute for phosgene, which is a gas and diphosgene, which is a liquid. [5] [6] Triphosgene is stable up to 200 °C. [7] Triphosgene is used in a variety of halogenation reactions. [8]
The daily Svenska Dagbladet newspaper said authorities had found traces of phosgene. The gas has a strong odor that can cause vomiting and breathing trouble and was used as a weapon in World War I.
The types of weapons employed ranged from disabling chemicals, such as tear gas, to lethal agents like phosgene, chlorine, and mustard gas. These chemical weapons caused medical problems. [ 3 ] This chemical warfare was a major component of the first global war and first total war of the 20th century.
