Nitrile \Ni"trile\ (? or ?), noun [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.

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), noun [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.

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.
