Dinitr amine

The y -phenylenediamiaes are easily obtained by dinitrating, followed by catalyticaHy hydrogenating, an aromatic hydrocarbon. Thus, the toluenediamiaes are manufactured by nitrating toluene with a mixture of sulfuric acid, nitric acid, and 23% water at 330°C which first produces a mixture (60 40) of the ortho and para mononitrotoluenes. Further nitration produces the 80 20 mixture of 2,4- and 2,6-dinitrotoluene. Catalytic hydrogenation produces the commercial mixture of diamiaes which, when converted to diisocyanates, are widely used ia the production of polyurethanes (see Amines, aromatic, DIAMINOTOLUENES) (22).

This change in editorial leadership has resulted, perhaps inevitably, in a change in editorial policy which is reflected in the contents of Volume 8. There has been a marked de-emphasis on the inclusion of organic parent compounds followed by an exhaustive and voluminous cataloging of azide, azido, azo, diazido, diazonium, diazo, nitro, dinitro, polynitro, hitr amine, nitrate (esters and salts), dinitrate, poly nitrate, nitroso, polynitroso, chlorate, perchlorate, peroxide, picrate, etc, derivatives — regardless of whether any of these derivatives exhibit documented explosive or energetic properties. Only those materials having such properties have been included in this volume... 

In addition to the Ross-Schiessler process, utilising p-CH20 and AN, the synthesis of RDX/ HMX mixts has also been reported starting with other smail molecules (Ref 7), namely, methyl-amine nitrate methylene diamine dinitrate and nitramine (NH2N02) in combination with CH20. In these reactions, the intermediate formation of Hexamine or a cyclic analog, is not necessarily established...

Most dinitroanilines are synthesized from a precursor which is nitrated and subsequently aminated to yield the desired product. In the case of trifluralin, 4-chlorobenzo-trifluoride (PCBT) is dinitrated to yield 4-chloro-3,5-dinitro-a,a,a-triflurotoluene (Dinitro PCBT),...

In some more complex cases, secondary amines can be nitrated with nitrating mixtures. Diethanolnitramine dinitrate (DINA), for example, can be prepared by the action on diethanolamine of a mixture of nitric acid, nitric anhydride and zinc chloride (this is dealt with in more detail on p. 10).

Ethanolamine nitric ester nitrate (ethanolamine dinitrate) N03NH3CH2CH20N02 is a solid melting at 103°C. According to Naoum this compound can be prepared by nitrating ethanolamine [68], Aubry [69] has reported that a yield of 90-96% can be achieved in this reaction. This method of preparation has not been confirmed by some authors. Serious disadvantages of the substance include its inclination to absorb moisture, and the readiness with which it loses nitric acid owing to the wealdy basic properties of the amine [70],... 

The first true dimercury(I) nitrogen compound was obtained by the reaction of diacetylhydra-zide (NH acidic) with dimercury(I) dinitrate in aqueous solution.31 This compound is an amide and contains tricoordinated nitrogen atoms.91 Dimercurated amines with tetracoordinated nitrogen atoms have been obtained by reactions of amines of lower basicities with dimercury(I) salts.

Aziridinyl ketones can be synthesized from unsaturated carbonyls using a series of other methods. For example, azabicyclo[4.1.0]heptanone 27 was obtained from cyclohexenone 25 in its reaction with TV-bromotoluenesulfona-mide sodium salt 33 [49] (Scheme 1.10). The reaction of chalcone with N-chlorotoluenesulfonamide in the presence of silver nitrite is described in [50]. Trans-Aziridinyl ketone 18 was synthesized by reacting chalcone 22 with N,N-diamino-l,4-diazoniabicyclo[2.2.2.]octane dinitrate 34 and sodium hydride in 2-propanol [30, 51]. Aziridinyl ketones can be obtained in the reaction of a -unsaturated ketones with A,A-dichlorosulfonamines [52] and with amines in the presence of lead tetraacetate and trifluoroacetic acid [53] or in the presence of triethylammonium acetate under electrochemical reaction conditions [54]. 

Heating 4-(4-acetamidophenyl) imidazole with 3 M nitric acid at 85°C forms the dinitrate salt of the corresponding amine, but the use of 5 M acid gives 4-(4-amino-3,5-dinitrophenyl) imidazole (41) (79AKZ475). 

Distances between the bridgehead amines vary according to the topicity of the receptors. For monotopic complexes, the bridgehead distances are between 6.5 and 7.9 A. In terms of incorporating multiple species, however, the azacryptands appear to be the most flexible, as seen additionally in the dinitrate structure with 5 [30]. When... 

Historical RDX was first synthesized by Henning (GerP 104280 of 1899) for medical use. He failed to nitrate hex amine directly with strong HNOa but first prepd hexamine dinitrate, CgH y 2N4-2HN03, by treating an aq soln of hexamine with nitric acid. The resulting wh crysts were collected, dried and added in small portions to HN03 (d 1.52)...
