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.
Based on research by Fritz Haber into chlorine as a weapon, the Nernst–Duisberg Commission investigated the feasibility of adding phosgene to chlorine gas, to increase its lethality. [4] Work by Richard Willstätter to supply the German army with protective equipment, enabled it to contemplate the use of the far more lethal combination of ...
The Bhopal disaster or Bhopal gas tragedy was a chemical accident on the night of 2–3 December 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India.
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.
The release of green leaf volatiles following the cutting of a lawn is responsible for the odour of freshly cut grass.. The smell of freshly cut grass is an odour caused by green leaf volatiles (GLVs) released when it is damaged.
In 1989, the United States Environmental Protection Agency (EPA) considered using data from Nazi research into the effects of phosgene gas, believing the data could help US soldiers stationed in the Persian Gulf at the time. They eventually decided against using it, on the grounds it would lead to criticism and similar data could be obtained ...
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).
