Cyanin to Cylinder
(Cy"a*nin) n. [See Cyanic.] (Chem.) The blue coloring matter of flowers; called also anthokyan
(Cy"a*nine) n. (Chem.) One of a series of artificial blue or red dyes obtained from quinoline
and lepidine and used in calico printing.
(Cy"a*nite) n. [See Cyanic.] (Min.) A mineral occuring in thin- bladed crystals and crystalline
aggregates, of a sky-blue color. It is a silicate of aluminium. [Written also kyanite.]
(Cy*an"o*gen) n. [Gr. ky`anos a dark blue substance + -gen: cf. F. cyanogène. 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 which was one of the first compound radicals recognized.
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.
(Cy`a*nom"e*ter) n. [Gr. ky`anos a dark blue substance + -meter: cf. F. cyanomètre.] An
instrument for measuring degress of blueness.
(Cy`a*nop"a*thy) n. [Gr. ky`anos a dark blue substance + pa`qos affection.] (Med.) A
disease in which the body is colored blue in its surface, arising usually from a malformation of the heart,
which causes an imperfect arterialization of the blood; blue jaundice.
(Cy*an"o*phyll) n. [Gr. ky`anos a dark blue substance + fy`llon leaf.] (Bot.) A blue coloring
matter supposed by some to be one of the component parts of chlorophyll.
(Cy"a*nosed) a. [See Cyanic.] Rendered blue, as the surface of the body, from cyanosis or
deficient aëration of the blood.
(||Cy`a*no"sis) n. [NL. See Cyanic.] (Med.) A condition in which, from insufficient aëration of
the blood, the surface of the body becomes blue. See Cyanopathy.
(Cy*an"o*site) n. [See Cyanic.] (Min.) Native sulphate of copper. Cf. Blue vitriol, under
(Cy`a*not"ic) a. (Med.) Relating to cyanosis; affected with cyanosis; as, a cyanotic patient; having
the hue caused by cyanosis; as, a cyanotic skin.
(Cy*an"o*type) n. [Cyanide + -type.] A photographic picture obtained by the use of a cyanide.
(Cy"an"u*rate) n. (Chem.) A salt of cyanuric acid.
(Cy*an"u*ret) n. (Chem.) A cyanide. [Obs.]
(Cy`a*nu"ric) a. [Cyanic + uric: Cf. F. cyanurique.] (Chem.) Pertaining to, or derived from,
cyanic and uric acids.
(Cyanuric acid) (Chem.), an organic acid, C3O3N3H3, first obtained by heating uric
acid or urea, and called pyrouric acid; afterwards obtained from isocyanic acid. It is a white crystalline
substance, odorless and almost tasteless; called also tricarbimide.
