Organic peroxides in general are sensitive, dangerous explosives, and all forms of acetone peroxide are sensitive to initiation. TATP decomposes explosively; examination of the explosive decomposition of TATP at the very edge of detonation front predicts "formation of acetone and ozone as the main decomposition products and not the intuitively expected oxidation products." Very little heat is created by the explosive decomposition of TATP at the very edge of the detonation front; the foregoing computational analysis suggests that TATP decomposition as an entropic explosion. However, this hypothesis has been challenged as not conforming to actual measurements. The claim of entropic explosion has been tied to the events just behind the detonation front. The authors of the 2004 Dubnikova et al. study confirm that a final redox reaction (combustion) of ozone, oxygen and reactive species into water, various oxides and hydrocarbons takes place within about 180 ps after the initial reaction - within about a micron of the detonation wave. Detonating crystals of TATP ultimately reach temperature of and pressure of 80 kbar. The final energy of detonation is about 2800 kJ/kg (measured in helium) - enough to -"briefly"- raise the temperature of gaseous products to . Volume of gases at STP is 855 l/kg for TATP and 713 l/kg for DADP (measured in helium).
