Nitrile \Ni"trile\ (? or ?), n. [See Nitro-.] (Chem.)
   Any one of a series of compounds bearing the cyanide radical
   (-CN); particularly, one of those cyanides of alcohol
   radicals which, by boiling with acids or alkalies, produce a
   carboxyl acid, with the elimination of the nitrogen as
   ammonia.
   [1913 Webster]

   Note: The nitriles are named with reference to the acids
         produced by their decomposition, thus, hydrocyanic acid
         is formic nitrile, methyl cyanide is acetonitrile
         (also acetic nitrile), and ethyl cyanide is
         propionitrile (from propionic acid).
         [1913 Webster +PJC]

Cyanogen \Cy*an"o*gen\ (s?-?n"?-j?n), n. [Gr. ky`anos a dark
   blue substance + -gen: cf. F. cyanog[`e]ne. So called because
   it produced blue dyes.] (Chem.)
   A colorless, inflammable, poisonous gas, C2N2, with a
   peach-blossom odor, so called from its tendency to form blue
   compounds; obtained by heating ammonium oxalate, mercuric
   cyanide, etc. It is obtained in combination, forming an
   alkaline cyanide when nitrogen or a nitrogenous compound is
   strongly ignited with carbon and soda or potash. It conducts
   itself like a member of the halogen group of elements, and
   shows a tendency to form complex compounds. The name is also
   applied to the univalent radical, CN (the half molecule of
   cyanogen proper), which was one of the first compound
   radicals recognized.
   [1913 Webster]

   Note: Cyanogen is found in the commercial substances,
         potassium cyanide, or prussiate of potash, yellow
         prussiate of potash, Prussian blue, Turnbull's blue,
         prussic acid, etc.
         [1913 Webster]
