     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.
