(Ni`tro*ben"zene) n. [Nitro- + benzene.] (Chem.) A yellow aromatic liquid produced by
the action of nitric acid on benzene, and called from its odor imitation oil of bitter almonds, or essence
of mirbane. It is used in perfumery, and is manufactured in large quantities in the preparation of aniline.
Fornerly called also nitrobenzol.
(Ni`tro*ben"zol, Ni`tro*ben"zole), ( or ) , n. See Nitrobenzene.
(Ni`tro*cal"cite) n. [Nitro- + calcite.] (Min.) Nitrate of calcium, a substance having a grayish
white color, occuring in efflorescences on old walls, and in limestone caves, especially where there exists
decaying animal matter.
(Ni`tro*car"bol) n. [Nitro- + carbon + L. oleum oil.] (Chem.) See Nitromethane.
(Ni`tro*cel"lu*lose`) n. [Nitro- + cellulose.] (Chem.) See Gun cotton, under Gun.
(Ni`tro-chlo"ro*form) n. [Nitro- + chloroform.] (Chem.) Same as Chlorpicrin.
(Ni"tro*form) n. [Nitro- + formyl.] (Chem.) A nitro derivative of methane, analogous to chloroform,
obtained as a colorless oily or crystalline substance, CH.(NO2)3, quite explosive, and having well-defined
(Ni`tro*gel"a*tin) n. [Nitro- + gelatin.] An explosive consisting of gun cotton and camphor
dissolved in nitroglycerin. [Written also nitrogelatine.]
(Ni`tro*gen) n. [L. nitrum natron + -gen: cf. F. nitrogène. See Niter.] (Chem.) A colorless
nonmetallic element, tasteless and odorless, comprising four fifths of the atmosphere by volume. It is
chemically very inert in the free state, and as such is incapable of supporting life (hence the name azote
still used by French chemists); but it forms many important compounds, as ammonia, nitric acid, the
cyanides, etc, and is a constituent of all organized living tissues, animal or vegetable. Symbol N. Atomic
