phosgene
n 1: a colorless poisonous gas that smells like new-mown hay;
used in chemical warfare

Phosgene \Phos"gene\, a. [Gr. fw^s light the root of
gi`gnesqai to be born: cf. F. phosg[`e]ne.] (Old Chem.)
Producing, or produced by, the action of light; -- used
specifically to designate a gas also called carbonyl
chloride. See {phosgene}, n., and {Carbonyl}.
[1913 Webster PJC]


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 World War it was also used as a poisonous gas in
combat.
[PJC]


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.
[1913 Webster]

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.
[1913 Webster]

{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.
[1913 Webster PJC]
