| 释义 |
Yellow Cross (Gelbkreuz) is a World War I chemical warfare agent usually based on 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% sulfur mustard, 10% bis(chloromethyl) ether, and 10% tetrachloromethane. A later formulation, Gelbkreuz 1, was a mixture of 40% ethyldichloroarsine, 40% ethyldibromoarsine, and 20% of bis(chloromethyl) ether. In some cases nitrobenzene was used to mask the material's characteristic odor. French "ypérite no.20" was a similar mixture of 80% sulfur mustard and 20% tetrachloromethane. Yellow Cross is also a generic World War I German marking for artillery shells with chemical payload affecting exposed surfaces of the body. [1] See also
