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.
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]
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 ...

A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
MOSCOW (Reuters) -Russia said on Wednesday that relations with Washington were so confrontational that Russian citizens should not visit the United States, Canada and some EU countries in coming ...
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).
