Other preparations include the hydrolysis of nitrocarbamic acid (316), the reaction of NaSOs NH2 with concentrated nitric acid, (317) and the reaction of N2O5 with two equivalents of ammonia (318) (see Scheme 34). [Pg.3071]

Nitramine (161), the simplest member of the nitramines, can be prepared from ethyl carbamate (158) in three synthetic steps nitration of the latter with mixed acid or a solution of ethyl nitrate in concentrated sulfuric acid, followed by isolation of the resulting ethyl N-nitrocarbamate as the ammonium salt (159), hydrolysis with aqueous potassium hydroxide and subsequent acidification, yields nitramine (161). ... [Pg.229]

Methylnitramine (1) has also been synthesized from the hydrolysis of ethyl Ai-methyl-A -nitrocarbamate (163), Al,Al -dinitro-Ai,Ai -dimethyloxamide (9) and A Ai -dinitro-Ai.Al -dimethylurea (165) " the latter, synthesized from the mixed acid nitration of N,N -dimethylurea (164), has been suggested as a possible industrial route to methylnitramineX" ...

Nitroamide, the simplest of the nitroamines, is formed by the action of dilute acid on potassium nitrocarbamate, which itself results from the nitration of urethane and the subsequent hydrolysis of the nitro ester by means of alcoholic potassium hydroxide. [Pg.369]

In 1894, J. Thiele and A. Lachman 10 prepared nitramide, nr nitroxyl amide, NH2.N02, i.e. H2N202, isomeric with hyponitrous acid. They found that by adding a soln. of potassium hydroxide to a cone. aq. soln. of nitrourethane, N02.NH.C00C2H5, at 0°, potassium nitrocarbamate, N02.NH.C00K, separates... [Pg.268]

Potassium nitrocarbamate (9.1 g.) is weighed on glazed paper and, with the aid of a porcelain or platinum spatula, is added in very small portions to the cold dilute sulfuric acid. The solution is swirled continuously. Whenever the ice melts, the flask is immersed in the cold bath until ice again forms. [Pg.72]

Nitramide can be prepared by the decomposition of potassium nitrocarbamate in an acidic medium ... [Pg.3071]

The reaction of acid with potassium nitrocarbamate results in the formation of nitramide (equation 15.107) which is an isomer of hyponitrous acid. Nitramide has been structurally characterized one N atom is trigonal planar (O2AN) and the other is trigonal pyramidal (H2AN)- The compound is potentially explosive, and undergoes base-catalysed decomposition to N2O and H2O.
