Concise Encyclopedia Chemistry
Hydrazine hydrate At high temperatures, H. decomposes, often explosively, into
ammonia and nitrogen: 3 N2H4 — > 4 NH3 + N->. It burns in air, releasing a
large amount of heat: N2H4 + O2 -> N2 + 2 H2O. It is miscible with water in any ...
The hydrazine slowly formed according to eqn. (2) can react with chloramine
according to the reaction: N2H4 + 2NH2C1-»N, + 2NH4C1 (4) (p. 637) and is
therefore, like NH2C1, only an intermediate stage in the oxidation of ammonia by
...

Amines: Synthesis, Properties and Applications
Once formed chloramine reacts with ammonia to form hydrazine. H3N + C1-NH2
-> H2N-NH2 + HCl Unfortunately hydrazine also reacts with chloramine and
competes with ammonia in the second stage of the reaction. N2H4 + 2NH.C1 ->
N2 ...

Hydrazine is a known animal carcinogen and a suspected carcinogen for people.
Hydrazinereacts with many materials, andcare mustbe exercised toavoid storage
contact with materials that cause a decomposition (see Refs. 7.9 and 7.10).
George P. Sutton, Oscar Biblarz, 2011
Hydrazine is often used as a rocket fuel because it can be stored conveniently as
a liquid and it reacts very exothermically with oxygen, forming purely gaseous
products. AWe = -622kJ It has been suggested that hydrazine/fluorine mixtures ...

Whether hydrazine was also biodegraded remained an open question. When
emitted on land, hydrazine will volatilize and partially penetrate in the subsurface
of soils. In these soils the compound can absorb to soil particles before being ...

The refining area has five steps: 1) ammonia removal, 2) NaC1 concentration
and removal, 3) hydrazine-water distillation to reach azeotropic concentration, 4)
extractive distillation with aniline to break the azeotrope and 5) distillation to ...

Comprehensive Organic Synthesis: Reduction
A detailed investigation of selectivity in the catalytic reduction of (nitroaryl)
alkyinitriles with hydrazine and metal catalysis has been carried out.68 On a
small scale, selective reduction of (nitroaryl)alkyl- nitrile (13) to either (aminoaryl)
alkylnitrile ...

Chemical Demonstrations: A Handbook for Teachers of Chemistry
Solutions of hydrazine should not be mixed with bases, because doing so will
liberate hydrazine vapor. Hydrazine is a suspected carcinogen. Copper
compounds can be toxic if taken internally, and dust from copper compounds can
irritate ...
