Tetranitropropane diurea is a white crystal solid with a density of 1.93 g/cm. This compound exhibits better hydrolytic stability than similar compounds. It is stable in neutral and acidic medium while immediate decomposition was observed in alkaline medium (0.1 M NaOH). The compound was further characterized for its preliminary explosive properties (Table 1). The results show that the compound itself is sensitive to both impact and fiiction but it has high thermal stability. TNPDU has a relatively small particle size of 32 pm with a typical broad distribution and exhibits often two distinct modes. The size meets the requirements for propellant and explosive formulations. 

The Effect of Reaction Temperature on Explosion Properties Due to the hydration reaction, nitration reaction, and oxidation reaction between toluene and nitric acid, significant amount of heat is often released after toluene and nitric acid are mixed, which naturally makes the reaction temperature rise sharply. At the same time, reaction temperature can not only contribute to the composition of final products, but also affect their explosion properties. Table 7.33 showed the explosion properties of explosives prepared between 75-80 °C and below 50 °C.

A preliminary indication of the potential hazards can be estimated by knowing something about the chemical structure. Specific functional groups that contribute to the explosive properties of a chemical through rapid combustion or detonation are illustrated in Table 13-1. 

Detonation in Slurry Explosives. Cook, in his book, pp 316-21, described under the heading "Water-Compatible Explosives properties of slurry explosives developed by M.A. Cook.St H.E. Farnam. These expls were intended for use in large diameter underwater blasting at Iron Ore Company of Canada s Knob Lake operation. The success of these expls brought out the importance of pressure and density on the products of detonation. Table 12.21 of Cook s book gave computed properties of three dry versus water soaked slurry mixtures at AN/TNT ratios of zero, 1.0 8c 3.25. It was of interest to note that the computed (dry basis) available energy A of the TNT in slurry with 27% water was 17% greater...

Some explosive formulations based on HMX, HMX and NTO, HMX and TATB (by wt.) and binder have been studied for density, VOD, IAD (number of cards), initiation sensitivity, ignition temperature and other explosive properties. The data given in Table 2.9 and Table 2.10 show a significant decrease in sensitivity, IAD (number of cards) and initiation sensitivity of explosive formulations with an increase in the proportion of NTO as well as TATB. However, performance of the NTO-based formulation is slightly better [222].

Urbanski and Kapuscinski [57] found the following values for the explosive properties of nitroguanidine (Tables 5 and 6). 

The infra-red spectra of the heavy metal azides, which are the most interesting because of their explosive properties, were investigated by Gamer and Gomm [37], Lecomte et al. [38], and the Raman spectra have been studied by Kohlrausch and Wagner [36], and by Deb and Yoffe [26]. The results are given in Table 29. 

Martin carried out extensive research into the explosive properties of the azides of various metals (Table 33). The high sensitiveness of cuprous azide to impact is noteworthy.

A systematic approach to the relationship between the explosive properties of a molecule and its structure was proposed by van t Hoff in 1909 and Piets in 1953. According to Piets, the explosive properties of any substance depend upon the presence of definite structural groupings. Piets divided explosives into eight classes as shown in Table 2.1.

T. Urbanski and Kowalski [34] examined the properties of those perchlorates as well as a range of others, not previously described, to determine their sensitiveness, stability, and explosive strength (Table 115). 

T. Urbanski and Kowalski [34] have studied the explosive properties of pyridine perchlorate as well as quinoline and its nitro derivative perchlorates. Due to the introduction of a nitro group the sensitiveness to shock of the quinoline perchlorate increased, but to a smaller extent than the authors had previously observed with primary aromatic amines. The introduced nitro group markedly favoured the increase of explosive strength of the perchlorates (Table 116).

The explosive properties of nitrobenzene-tetranitromethane solutions were examined in detail by Roth [62] who measured rates of detonation power (on a 10.5 by 7 mm crusher gauge), and sensitiveness to impact, using nitroglycerine and TNT as standards (Table 129). Lead block expansions are not included here as they were not determined by standard methods.
