Properties that cause explosion hazard of organic peroxides, hydroperoxides and nitrocompounds are examined in the article. Ability to thermal explosion initiation of benzoyl peroxide and of nitrocompounds is compared. Explosion properties of peroxides are analyzed. Measurements of burning temperature by means of micro thermocouples and the comparison of their values with the calculated ones of benzoyl peroxide and hydroperoxide of isopropyl benzene lead to the conclusion that burning of them propagates in condensed phase. It is noted that heat instability of benzoyl peroxide burning, contrary to many nitrocompounds, is absent. Burning of benzoyl peroxide is stable even in vacuum. It is noted that, although benzoyl peroxide is not applied as explosive, in some cases the explosion hazard of benzoyl peroxide heating can be bigger than that of PETN. This conclusion was made on the basis of an investigation carried out by means of DSC method. The explosion process of benzoyl peroxide and hydroperoxide of isopropyl benzene propagates in a regime reminiscent of a low velocity detonation and the explosive effects are suffcient for severe destructions during accidents. This conclusion unfortunately is confrmed by bitter experience in practice. The results of the investigation of condensed products of explosion at impact of mixtures aluminum with peroxides and with nitrocompounds by means of impact-testing machine that were carried out in this work by X-ray diffraction analysis are discussed. It was shown that if the temperature of explosion of a mixture is Tp ≥ 2200-2300 K, practically all aluminum or aluminum hydride in the mixture transformed into aluminum oxide.
