Yellow Cross (Gelbkreuz) is a World War I chemical warfare agent usually based on mustard gas (sulfur mustard, HS, Yperite, Lost). The original Gelbkreuz was a composition of 80–90% of sulfur mustard and 10–20% of tetrachloromethane or chlorobenzene as a solvent which lowered its viscosity and acted as an antifreeze , or, alternatively, 80% ...
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 ...
A Canadian soldier with mustard gas burns, 1917/1918. Mustard gas is not an effective killing agent (though in high enough doses it is fatal) but can be used to harass and disable the enemy and pollute the battlefield. Delivered in artillery shells, mustard gas was heavier than air, and it settled to the ground as an oily liquid.
In 2012 SITA UK started redevelopment of the site, but after construction workers were affected by mustard-gas type symptoms, the Ministry of Defence were called in to test and approve the site. However, after MoD approval, a few months later construction workers found a mustard gas shell, which was disposed of by the 11 Explosive Ordnance ...
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 ...
The Rawalpindi experiments were experiments involving use of mustard gas carried out by British scientists from Porton Down on hundreds of soldiers from the British Indian Army. These experiments were carried out before and during the Second World War in a military installation at Rawalpindi, in modern-day Pakistan. [1]

Despite repeated denials that mustard gas had been present on any Allied ships in the harbor, Alexander was able to determine that a ship loaded with mustard gas shells had blown up and that the mustard gas had mixed with the oil floating in the harbor, which acted as a solvent and allowed the chemical warfare agent to be absorbed into the skin ...
