hydrazine
(encz) | hydrazine,hydrazin n: Zdeněk Brož |
Hydrazine
(gcide) | Hydrazine \Hy"dra*zine\, n. [Hydr- + azo- + -ine.] (Chem.)
Any one of a series of nitrogenous bases, resembling the
amines and produced by the reduction of certain nitroso and
diazo compounds; as, methyl hydrazine, phenyl hydrazine, etc.
They are derivatives of hydrazine proper, H2N.NH2, which is
a doubled amido group, recently (1887) isolated as a stable,
colorless gas, with a peculiar, irritating odor. As a base it
forms distinct salts. Called also diamide, amidogen, (or
more properly diamidogen), etc.

Phenyl hydrazine
(gcide) | Phenyl \Phe"nyl\, n. [Gr. fai`nein to bring to light + -yl: cf.
F. ph['e]nyle. So called because it is a by-product of
illuminating gas.] (Chem.)
A hydrocarbon radical (C6H5) regarded as the essential
residue of benzene, and the basis of an immense number of
aromatic derivatives.
[1913 Webster]
Phenyl hydrate (Chem.), phenol or carbolic acid.
Phenyl hydrazine (Chem.), a nitrogenous base
(C6H5.NH.NH2) produced artificially as a colorless oil
which unites with acids, ketones, etc., to form easily
crystallized compounds. It is used in organic chemistry,
particulary to isolate compounds in pure form for
analysis.
