Dartnell, R. C. et al., Loss Prev., 1971, 5, 53-56 MCA Case History No. 1649 A batch of 8 t of material accumulated in storage at 154°C during 72 h decomposed explosively. Stability tests showed that thermal instability developed when 3-methyl-4-nitrophenol is stored molten at temperatures above 140°C. Decomposition set in after 14 h at 185° or 45 h at 165°, with peak temperatures of 593 and 521°C, respectively. In a closed vessel, a peak pressure of 750 bar was attained, with a maximum rate of increase of 40 kbar/s. Thermal degradation involves an initially slow exothermic free radical polymerisation process, followed by a rapid and violently exothermic decomposition at take-off. 

Cyanide blood agents are relatively unstable and tend to polymerize on standing. Polymers can be explosive. Stabilizers or solvents can be added to inhibit decomposition. Stabilizers include phosphoric acid, sulfuric acid, powdered sodium pyrophosphate, and sulfur dioxide. Although cyanide blood agents react with metals, they can be stored in steel or other common containers if stabilized. 

Detonation (and Explosion), Stability of Explosives. Andreev 8t Belyaev (Ref 1, p 106) stated that stability, of explosive (stoykost vzryvchatogo veshchestva) is determined by the rate of changes in its physical and chemical (and consequently of explosive) properties with duration of time. The smaller the rate, the more stable is explosive and vice versa... 

Explosive compounds are rarely found in the pure state they are frequently combined with other explosives, stabilizers, tagging agents, plasticizers, and other modifiers to increase the stability and efficiency of the explosive product in question. Over three dozen commercial products with the desired properties, as represented in Table 3, can be shown to share thress major target VOCs also listed [29,30],... 

TNB is an excellent explosive. It has almost all of the virtues wanted in an explosive stability, low toxicity, nonsensitivity, relatively high output velocity and pressure. We use very little of this explosive, however, because it is extremely difficult to synthesize and hence is very expensive.

Suspension systems of sticky slurry and paste-like liquid explosives with solid particles, based on the dispersion of suspended solid particles, should belong to suspension or coarse multiphase systems in colloid chemistry. In these suspension systems, the main issue is its dynamic instability, because the density of the dispersed particles and the density of the dispersion medium are different (generally, the density particle is greater than that of the medium), settlement or floating can occur with the role of gravitational field to separate the system, resulting in unevenness in composition and density of liquid explosive. Stability is the ability to overcome the so-called sink-and-float separation of two-phase components, therefore, within a certain period of use, the composition and density of explosive and other physical parameters remained unchanged and its properties are stable and reliable. 

However, the other two sluny and pasty explosives stabilize aluminum powder and RDX particles in the mixture system through dissolving polymer nitrocellulose (1—2 %) in nitroalkanes.
