Mustard gas or sulfur mustard are names commonly used for the organosulfur chemical compound bis(2-chloroethyl) sulfide, which has the chemical structure S(CH 2 CH 2 Cl) 2, as well as other species. In the wider sense, compounds with the substituents −SCH 2 CH 2 X or −N(CH 2 CH 2 X) 2 are known as sulfur mustards or nitrogen mustards ...
During experiments with ethylene and sulfur dichloride in 1860, Niemann produced mustard gas. He was among the first to document its toxic effects, [5] but he might have not been the first to synthesize it. [6] In 1860 and almost in parallel to Niemann, Frederick Guthrie reported the same reaction as Niemann. [5]
The idealized combustion of mustard gas in oxygen produces hydrochloric acid and sulfuric acid, in addition to carbon dioxide and water: (ClC 2 H 4) 2 S + 7 O 2 → 4 CO 2 + 2 H 2 O + 2 HCl + H 2 SO 4. Bis(2-chloroethyl)sulfide reacts with sodium hydroxide, giving divinyl sulfide: (ClC 2 H 4) 2 S + 2 NaOH → (CH 2 =CH) 2 S + 2 H 2 O + 2 NaCl ...
Fritz Haber (German: [ˈfʁɪt͡s ˈhaːbɐ] ⓘ; 9 December 1868 – 29 January 1934) was a German chemist who received the Nobel Prize in Chemistry in 1918 for his invention of the Haber process, a method used in industry to synthesize ammonia from nitrogen gas and hydrogen gas.
Guthrie was probably not the first to synthesize mustard gas, but he was among the first to document its toxic effects. Guthrie did his mustard gas synthesis at almost the same time as Albert Niemann , who also synthesized mustard gas and noted its toxic effects in his own experiments. [ 5 ]
The proportion of mustard gas fatalities to total casualties was low; 2% of mustard gas casualties died and many of these succumbed to secondary infections rather than the gas itself. Once it was introduced at the third battle of Ypres, mustard gas produced 90% of all British gas casualties and 14% of battle casualties of any type.
Canada invented canola, and many cooks swapped out dangerous trans fats for this cheaper, more accessible oil. Food producers also started making ultra-processed foods with things like canola oil ...
The whole affair was kept secret at the time and for many years after the war. According to the U.S. military account, "Sixty-nine deaths were attributed in whole or in part to the mustard gas, most of them American merchant seamen" [102] out of 628 mustard gas military casualties. [103]
