Other historical lab routes include methylation of hydrazine, reduction of nitrodimethylamine and amination of dimethylamine with aminopersulfuric acid. [11] UDMH is produced industrially by two routes. [5] Based on the Olin Raschig process, one method involves reaction of monochloramine with dimethylamine giving 1,1-dimethylhydrazinium chloride:
Dimethylhydrazine is the name of two compounds with the molecular formula C 2 H 8 N 2.These are: unsymmetrical dimethylhydrazine (1,1-dimethylhydrazine), with both methyl groups bonded to the same nitrogen atom
The reduction of benzenediazonium chloride with tin(II) chloride and hydrochloric acid provides phenylhydrazine. [2] 2,4-Dinitrophenylhydrazine is produced by the reaction of 1-chloro-2,4-dinitrobenzene with hydrazine. [2] Tetraphenylhydrazine is formed by the oxidation of diphenylamine with potassium permanganate in acetone. [2]
Aerozine 50 is a 50:50 mix by weight of hydrazine and unsymmetrical dimethylhydrazine (UDMH), [1] [2] developed in the late 1950s by Aerojet General Corporation as a storable, high-energy, hypergolic fuel for the Titan II ICBM rocket engines.
Devil's venom was a nickname coined by Soviet rocket scientists for a hypergolic liquid rocket fuel composed of a dangerous combination of red fuming nitric acid (RFNA) and unsymmetrical dimethylhydrazine (UDMH). [1]
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).
Symmetrical dimethylhydrazine (SDMH), or 1,2-dimethylhydrazine, is the organic compound with the formula (CH 3 NH) 2.It is one of the two isomers of dimethylhydrazine.Both isomers are colorless liquids at room temperature, with properties similar to those of methylamines.
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 ...
