Dinitrogen tetroxide, commonly referred to as nitrogen tetroxide (NTO), and occasionally (usually among ex-USSR/Russian rocket engineers) as amyl, is the chemical compound N 2 O 4. It is a useful reagent in chemical synthesis. It forms an equilibrium mixture with nitrogen dioxide. Its molar mass is 92.011 g/mol.
Pentaborane(9) and diborane + nitrogen tetroxide – Pentaborane(9), a so-called Zip fuel, was studied by Soviet Rocket Scientist V. P. Glushko for usage in combination with nitrogen tetroxide in the RD-270M rocket engine. This propellant combination would have yielded a significant increase in performance, but was ultimately given up due to ...
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).
Mixed oxides of nitrogen (MON) are solutions of dinitrogen trioxide (N 2 O 3) in dinitrogen tetroxide/nitrogen dioxide (N 2 O 4 and NO 2). It may be used as an oxidizing agent in rocket propulsion systems. [1] Mixed oxides of nitrogen are produced by dissolving nitric oxide (NO) gas in liquid dinitrogen tetroxide. Nitric oxide reacts with ...
2 converts to colourless dinitrogen tetroxide (N 2 O 4) ... This is a redox reaction and thus nitric oxide and nitrogen are also produced as byproducts.
UDMH is often used in hypergolic rocket fuels as a bipropellant in combination with the oxidizer nitrogen tetroxide and less frequently with IRFNA (inhibited red fuming nitric acid) or liquid oxygen. [12] UDMH is a derivative of hydrazine and is sometimes referred to as a hydrazine. As a fuel, it is described in specification MIL-PRF-25604 in ...
This was historically used for reaction control systems, due to being easily storable. It is often used to drive Turbopumps, being used on the V2 rocket, and modern Soyuz. Hydrazine decomposes energetically to nitrogen, hydrogen, and ammonia (2N 2 H 4 → N 2 +H 2 +2NH 3) and is the most widely used in space vehicles. (Non-oxidized ammonia ...
The main complication with dissolving metals in nitric acid arises from redox reactions, which can afford either nitric oxide or nitrogen dioxide. Anhydrous nitrates can be prepared by the oxidation of metals with dinitrogen tetroxide (often as a mixture with nitrogen dioxide, with which it interconverts).
