Nitramines analysis

The Na salt of MEDINA was fluorinated in w, the sain extd with methylene chloride, and the solv evapd to give a yellow oil whose IR spectrum showed absence of NH and the presence of NF absorption, and analysis indicated was a mixt (Ref 22). Nitramines in the presence of sulfuric acid are capable of nitrating reactive aromatic compds, but when acetanilide was treated with MEDINA in the presence of this acid, no nitroacetanilide was isolated. Instead compds indicating that the MEDINA had been fragmented and the fragments reacted with the acetanilide were isolated (Ref 12)... [Pg.69]

The following examples illustrate the range of apphcations of LC/MS for trace analysis of explosives ESI-LC/MS/MS-CID fragmentation processes of a series of nitroaromatic, nitramine and nitrate ester explosives were studied in the negative-ion mode using daughter-ion, parent-ion and neutral loss scans [14]. Table 1 shows the CID daughter ions in ESI-MS/MS of TNT. [Pg.155]

The importance of cyclic nitramines as military explosives has meant that an enormous amount of research has been conducted in this area. Only some of the rich array of products and by-products obtainable from hexamine nitrolysis are discussed in this section. For mechanistic smdies and detailed analysis of these reactions the primary research papers should be consulted. " ... [Pg.243]

These inferences concerning the structure of nitramines, based on their chemical properties, are confirmed by the data obtained by X-ray analysis of the simple nitramines dimethylnitramine and ethylenedinitramine. In particular, Costain and Cox [1], and Llewellyn and Whitmore [2], established that the grouping... [Pg.2]

A final set of tests of this series of investigations focused on the analysis of hydrostatic compression of some representative energetic materials. Sorescu et al. [117] have considered the case of nitramine RDX (a-phase), HMX ((3-phase), and HNIW (e-phase) and the non-nitramine PETN crystal. These studies have been performed based on NPT-MD simulations at room temperature over the pressure ranges 0-4 GPa for RDX, 0-7.5 GPa for HMX, 0-3.5 GPa for HNIW, and 0-9 GPa for PETN. In the case of the RDX, HMX, and HNIW crystals, the results indicate that the proposed potential model is able to reproduce accurately the changes in the... [Pg.155]

By the negative chemical ionization (NCI) mass spectral method the negative ions of 2-nitroimidazole are obtained [1305], This method is much more sensitive than the positive chemical ionization one. The analytical potential of the NCI mass spectrometry for the analysis of different classes of nitro compounds has been discussed [1305], Mass spectra of 1,4-dinitro-, 2,4-dinitro-, and 4,5-dinitroimidazoles have been studied [1306], Comparisons of mass spectra (70 eV) of these compounds have shown that the fragment product ions have the same m/z values, but differ in their relative abundance and in the ion appearing the main peak. It seems that this difference is due to the nitramine functionality of 1,4-dinitroimidazole [1306]. [Pg.339]

A considerable number of X-ray examinations of nitro compounds have been done over the last two decades. They will be given in the description of particular compounds. However, the following are reviews which should be mentioned X-ray analysis of aliphatic nitro compounds, nitrate esters and nitramines were described by Novikov and co-workers [7], nitramines by G. F. Wright [115], polynitroaromatic addition compounds by Hall and Poranski [116]. The X-ray... [Pg.406]
