Nitramides

Nitroxylic acid, HiNO . Yellow NajNOa formed by electrolysis NaN02 in NHj. Structure unknown free acid unknown. Nitramide, H2NNO2. A weak acid. 

Figure 7-3. Br nsted plot for the decomposition of nitramide catalyzed by substituted anilines.

Thermal decomposition of nitramide, H2NNO2, or hyponitrous acid H2N2O2 (both of which have the empirical formula N2O.H2O) have also been used. The mechanisms of these and other reactions involving simple inorganic compounds of N have been reviewed.

Following three phase transformations [951] (>298 K), NH C decomposition begins [915] in the solid phase at 423 K but only becomes extensive well above the melting point ( 440 K). Decomposition with the evolution of N20 and H20 from the melt is first order [952,953] (E = 153—163 kJ mole-1), the mechanism suggested involving intermediate nitramide formation. Other proposed schemes have identified NOj [954] or the radical NH2NO [955] (<473 K) as possible participants. Studies [956,957] have been made of the influence of additives on NH C decomposition.

Salts of the acidic dinitramine find use as oxidants in propellant formulations. The dinitramine itself is explosively unstable, though more stable than nitramide [1], Although described as relatively stable the sodium salt has an autoignition temperature of 123°C, the potassium 140°C [2],... 

Nitramide is quite unstable and various reactions in which it is formed are violent. Attempts to prepare it by interaction of various nitrates and sulfamates showed that the reactions became explosive at specific temperatures. 

A drop of cone, alkali solution added to solid nitramide causes a flame and explosive decomposition. 

Nitramide decomposes explosively on contact with cone, sulfuric acid. 

Both hyponitrous acid and nitroamide (also known as nitramide) have the formula H2N202. Draw the structures for these molecules and explain any difference in acid-base properties.

Electron impact mass spectra of nitro compounds show generally [M — 0]+ ions, however, in low intensity. Several [M —0]+ ions, e.g. the [M— 16]+ of nitromethane44 and nitroethene45, has by tandem mass spectrometry unambiguously been demonstrated to be of the nitroso form. Particularly interesting is the use of the parent nitramide in NRMS study of the elusive nitrosamide46.
