COCl2
(gcide) | 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.

COCl2
(gcide) | 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] |
CoCl2
(gcide) | Cobaltous \Co*balt"ous\, a. (Chem.)
Pertaining to, derived from, or containing, cobalt; -- said
esp. of cobalt compounds in which the metal has its lower
valence.
[1913 Webster]
Cobaltous chloride, a crystalline compound, CoCl2, of a
pale rose color when hydrous, blue when dehydrated. Its
solution is used for a sympathetic ink, the writing being
nearly colorless when dried in the air, owing to absorbed
moisture, and becoming bright blue when warmed.
