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).
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can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou
N-Hydroxyphthalimide ethers, on the other hand, are colorless and provide O-alkylhydroxylamines by alkaline hydrolysis or cleavage through hydrazine hydrate. The "phthalylhydroxylamine" reported by Cohn was known to have a molecular formula of C 8 H 5 NO 3, but the exact structure was not known. [4]
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] −.
Industrially the compound is produced by treatment of urea with hydrazine: [3] OC(NH 2) 2 + 2 N 2 H 4 → OC(N 2 H 3) 2 + 2 NH 3. It can also be prepared by reactions of other C1-precursors with hydrazine, such as carbonate esters. [2] It can be prepared from phosgene, but this route cogenerates the hydrazinium salt [N 2 H 5]Cl and results in ...
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 ...
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 → ...
When derived from hydrazine itself, hydrazones condense with a second equivalent of a carbonyl to give azines: [10] R 2 C=N−NH 2 + R 2 C=O → R 2 C=N−N=CR 2 + H 2 O. Hydrazones are intermediates in the Wolff–Kishner reduction. Hydrazones are reactants in hydrazone iodination, the Shapiro reaction, and the Bamford–Stevens reaction to ...
