Phosgene was first deployed as a chemical weapon by the French in 1915 in World War I. [24] It was also used in a mixture with an equal volume of chlorine, with the chlorine helping to spread the denser phosgene. [25] [26] Phosgene was more potent than chlorine, though some symptoms took 24 hours or more to manifest.
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. The Schedule 3 list is one of three lists.
Unlike thiophosgene monomer, a red liquid, the photodimer, an example of a 1,3-dithietane, is a colourless solid. [7] Swarts fluorination of the dimer and then cracking is the principal route to thiocarbonyl fluoride. [8] Thiophosgene decomposes at 200 °C or above to form carbon disulfide and carbon tetrachloride. [9]
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 has a strong, disagreeable and irritating odor. It is used as a reagent in organic chemistry. [2]

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 ...
