Hydrazine is an inorganic compound with the chemical formula N 2 H 4.It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour.Hydrazine is highly hazardous unless handled in solution as, for example, hydrazine hydrate (N 2 H 4 ·xH 2 O).
It is an intermediate in some hydrazine manufacturing processes. Synthesis. Acetone azine can be prepared from acetone and hydrazine: [3] 2 (CH 3) 2 CO + N 2 H 4 → ...
Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. . Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou
The main advantage of the peroxide process to hydrazine relative to the traditional Olin Raschig process is that it does not coproduce salt. In this respect, the peroxide process is an example of green chemistry. Since many millions of kilograms of hydrazine are produced annually, this method is of both commercial and environmental significance ...
Hydrazine sulfate, more properly hydrazinium hydrogensulfate, is a salt of the cation hydrazinium and the anion bisulfate (hydrogensulfate), with the formula N 2 H 6 SO 4 or more properly [N 2 H 5] + [HSO 4] −.
Monomethylhydrazine (MMH) is a highly toxic, volatile hydrazine derivative with the chemical formula CH 6 N 2. It is used as a rocket propellant in bipropellant rocket engines because it is hypergolic with various oxidizers such as nitrogen tetroxide (N 2 O 4) and nitric acid (HNO 3). As a propellant, it is described in specification MIL-PRF ...
diazane (or hydrazine), N 2 H 4 - two nitrogen and four hydrogen triazane, N 3 H 5 - three nitrogen and five hydrogen. Azanes with three or more nitrogen atoms are named by adding the suffix-azane to the appropriate numerical multiplier prefix. Hence, triazane, N 3 H 5; tetrazane or tetraazane, N 4 H 6; pentazane or pentaazane, N 5 H 7 ...
Ketazines are also important intermediates in the industrial production of hydrazine hydrate by the peroxide process. [3] In the presence of an oxidant, ammonia and ketones react to give hydrazine via ketazine: 2 Me(Et)C=O + 2 NH 3 + H 2 O 2 → Me(Et)C=NN=C(Et)Me + 2 H 2 O. The ketazine can be hydrolyzed to the hydrazine and regenerate the ketone:
