Energetic compounds

The fluid plasticizer (solvent) consists of an energetic compound, eg, nitroglycerin, an inert carrier, and a stabilizer. The system is evacuated to remove volatiles, moisture, and air, and the plasticizer is then pressurized and passed slowly upward through the powder bed while the powder is held stationary by a pressure plate on the powder column. Casting solvent may also be added from the top of the mold. 

This reasoning is used systematically in the most complex cases by looking for the most energetic compounds that are likely to be formed. It leads to the descending order of priority of the degradation substances this is taken into account in the writing of the equation.

Highly energetic compounds with potential use in explosive devices must be characterized completely and safely, particularly as the explosive character may be linked directly to vibrational modes in the molecular structure, hence the application of computational methods to complement experimental observations. ANTA 5 has been the subject of various studies and, as an adjunct to one of these and to confirm the results of an inelastic neutron scattering experiment, an isolated molecule calculation was carried out using the 6-311G basis set <2005CPL(403)329>. 

Supplementary to other vibrational spectroscopies, inelastic neutron scattering (INS) spectroscopy is a very useful technique for studying organic molecules as it is extremely sensitive to the vibrations of hydrogen atoms. INS spectroscopy has been used to analyze the molecular dynamics of the energetic compound ANTA 5 <2005CPL(403)329>.

Low MW strained-ring furazan A-oxides (furoxans) and some of their precursors are highly energetic compounds and should be handled carefully with due caution [1], and preferably in solution [2], Benzofiiroxans are reviewed, especially in relation to their explosive properties, which may be superior to corresponding nitrocompounds in energy, speed of detonation and bulk density [3],... 

This large and well documented group of explosive compounds contains some which are widely used industrially [1]. The text gives a thorough treatment of all aspects of the physics and chemistry (Vol. 1) and of the applications (Vol. 2) of this important group of energetic compounds [2],... 

Some concentrated nitric acid may be produced as a by-product in the SILVER II process when processing energetics compounds, which contain nitrogen. The material will be collected and sold to off-site users. During Demo II testing, analysis of nitric acid samples by the Ensign-Bickford Company determined that the... 

Abstract- Results of experiments on Phytoremediation of Explosive and Energetic Compounds indicates that Phytoremediation is a promising technology for various levels of energetic compounds including TNT. This paper explores both the mechanisms and provides results of the work on phytoremediation.

This chapter is an extension of Chapter 1 and discusses the more recent research into energetic compounds which contain strained or caged alicyclic skeletons in conjunction with C-nitro functionality. This chapter complements Chapter 1 by providing case studies which show how the same methods and principles that introduce C-nitro functionality into simple aliphatic compounds can be used as part of complex synthetic routes towards caged polynitrocycloalkanes. The chemistry used for the synthesis of caged structures can be complex but the introduction of C-nitro functionality follows the same principles as discussed in Chapter 1. It is suggested that chemists who are not familiar with this field of chemistry consult Chapter 1 before reading this chapter. 

Some energetic compounds have picryl groups (2,4,6-trinitrophenyl-) introduced as substituents in the 3- and 4-positions of the furazan ring. Coburn synthesized a series of picrylamino-substituted furazans, including 4,4 -bis(picrylamino)-3,3 -bifurazan (BPABF) (34) from the reaction of 4,4 -diamino-3,3 -bifurazan (DABF) (32) with two equivalents of picryl fluoride. 

The tetraazapentalene ring system forms the core of the thermally insensitive explosive TACOT (Section 7.10) and so its fusion with the furoxan ring would be expected to enhance thermal stability and lead to energetic compounds with a high density, y-DBBD (95) is prepared from the nitration of tetraazapentalene (91), nucleophilic displacement of the o-nitro groups with azide anion, further nitration to (94), followed by furoxan formation on heating in o-dichlorobenzene at reflux. The isomeric explosive z-DBBD (96) has been prepared via a similar route. ... 

The two energetic A-nitroimide explosives (137) and (138) have been prepared from 1,2,3-triazole and 1,2,4-triazole respectively. These and other A-nitroimide-based energetic compounds are discussed in more detail in Section 6.11.3.
