phosgene \phos"gene\ (f[o^]s"j[=e]n or f[o^]z"j[=e]n), n. (Chem.) A reactive chemical substance ( COCl2), also called carbonyl choride, used in synthesis of numerous substances. In the First Worlds War it was also used as a poisonous gas in combat.
Carbonyl \Car"bon*yl\, n. [Carbon + -yl.] (Chem.) The radical (CO)'', occuring, always combined, in many compounds, as the aldehydes, the ketones, urea, carbonyl chloride, etc.
Note: Though denoted by a formula identical with that of carbon monoxide, it is chemically distinct, as carbon seems to be divalent in carbon monoxide, but tetravalent in carbonyl compounds.
Carbonyl chloride (Chem.), a colorless gas, COCl2, of offensive odor, and easily condensable to liquid. It is formed from chlorine and carbon monoxide, under the influence of light, and hence has been called phosgene, or phosgene gas; -- called also carbon oxychloride. It is used in chemical synthesis, and was also used as a poison gas in World War I.

Phosgene is the chemical compound with the formula COCl. This colorless gas gained infamy as a chemical weapon during World War I where it was responsible for about 85% of the 100,000 deaths caused by chemical weapons. It is also a valued industrial reagent and building block in synthesis of pharmaceuticals and other organic compounds. In low concentrations, its odor resembles freshly cut hay or grass. In addition to its industrial production, small amounts occur from the breakdown and the combustion of organochlorine compounds, such as those used in refrigeration systems. The chemical was named by combining the Greek words "phos" (meaning light) and "genesis" (birth); it does not mean it contains any phosphorus (cf. phosphine).

For a minute I am looking straight down at the moonlit phosgene clouds -- green as mustard gas in the lying moonlight -- then we are both racketing around a series of spirals, DNA-HELIX switchbacks, our sleds teetering on the edge of each bank so that twice my ice-axe blade bites into nothing but freezing air, but both times we drop back down and emerge -- not exiting the turns so much as being spit out of them, two rifle bullets fired just above the ice -- and then we bank high again, come out accelerating onto a straight, and shoot across eight kilometers of sheer ice wall on the .
