Four nitrosamines, seven nitramines, three nitroesters and the explosives Semtex 10 and Composition B have been investigated by TGA. Linear dependence was confirmed between the position of the TGA onsets, as defined in the sense of Perkin-Elmer s TGA-7 standard program, and the samples weights. The slope of this dependence is closely related to the thermal reactivity and molecular structure. The intercept values of the dependence correlate with the autoignition temperatures and with the critical temperatures of the studied compounds, without any clear influence from molecular structure. Results show that Semtex 10 exhibits approximately the same thermostability as its active component pentaerythrityl tetranitrate (PETN, 274). Results also show that TGA data for Composition B do not correlate with analogous data for pure nitramines564.

In reactivity, the red allotropic form of elemental phosphorus is intermediate to the black and white varieties. It does not ignite spontaneously. The autoignition temperature for RP is 260°C (500°F). When RP burns, the evaporated phosphorus condenses as WP, which creates fire (reignition) and is a health hazard. For this reason, RP fires should be thoroughly cleaned up. 

PERSADOX (94-36-0) Combustible solid (autoignition temperature 176°F/80°C). Power, dust, or vapor forms explosive mixture with air. Confined storage of dry chemical may lead to decomposition and explosion. A strong oxidizer extremely reactive with many substances. An explosive that is sensitive to friction, shock, and heat may decompose below the melting point of 217°F/103°C. Fire and/or explosions may result from contamination contact with strong acids, combustible materials, reducing agents, oxidizers, acids, bases, alcohols. 

Noncombustible liquid flash point (open cup) 115°C (240°F) autoignition temperature 398°C (748°F). The reactivity of this compound is low. Its reaction with concentrated sulfuric or nitric acids is vigorous (exothermic). 

Combustible liquid flash point (open cup) 55°C (131°E) vapor pressure 0.4 torr at 20°C (68°E) autoignition temperature 369°C (696°E) the vapor forms explosive mixtures with air LEE value 2.7% by volume of air, UEL value not reported fire-extinguishing agent dry chemical, foam, or CO2 use a water spray to keep fire-exposed containers cool, to disperse the vapor, and to blanket the fire. The reactivity of this compound toward most chemicals is low. 

A 75% solution in benzene or mineral spirits is the maximum assay that is sold commercially. Its benzene solution at this concentration is reactive, oxidizing, and flammable. The flash point varies depending on the solvent the autoignition temperature not reported the self-accelerating decomposition temperature is 93°C (199.4°F). 

Highly reactive and oxidizing compound with moderate flammability flash point (open cnp) 107-110°C (224.6-230°F) autoignition temperature not reported. 

Highly flammable solid autoignition temperature 100°C (212°F). It can ignite by friction. Fire-extinguishing agent CO2 use a flood of water to extinguish fire. Phosphorus sesquisulfide is decomposed by water. However, its reactivity toward water is not as violent as that of phosphorus pentasulfide.
