Sprengel explosives

Adsorption of perchloryl fluoride on charcoal can, like liquid oxygen, produce a powerful Sprengel explosive. 

Having shown that both Sprengel explosives and organic peroxides have been seriously studied, and in numerous cases applied as commercial energetic materials, their current status needs to be addressed. As stressed in each case, these materials were too unstable, unfriendly, and unpredictable for continued use in a field populated with much better alternatives. Terrorists, however, often do not have ready access to the commercial and military alternatives in use today. They are not deterred by the factors that forced the Sprengel explosives and the peroxides into mainstream obscurity. 

Late in the nineteenth century, Herman Sprengel patented a series of simple oxidation-reduction mixts for use in commercial blasting. These so-called Sprengel explosives typically consisted of coned nitric acid, or liquid N02, mixed with liq fuels such as nitrobenzene, carbon disulfide, petroleum, etc. They were intended to be mixed immediately before use. Because of handling difficulties Sprengel expls never became very popular (Refs 4 6)... 

The expl value of MNB is very low but when mixed with oxidizing agents, such as nitric acid or nitrogen peroxide, it produces very powerful expls(see Sprengel Explosives, Helhofite, etc). 

Blake Explosive, proposed in 1865 for filling grenades and torpedoes consisted of K chlorate and sulfur. It was the predecessor of Sprengel Explosives, known as Cheddites or Street Explosives Ref Stettbacher(1933),309... 

Nitrobenzene is a pale yellow liquid, b.p. 208.0°, which is poisonous and has an almondlike odor closely resembling that of benzaldehyde (which is not poisonous). It is used as a component of certain Sprengel explosives and as a raw material for the preparation of aniline and of intermediates for the manufacture of dyestuffs and medicinals. Its preparation, familiar to every student of organic chemistry, is described here in order that the conditions for the substitution of one nitro group in benzene may serve us more conveniently as a standard for judging the relative ease and difficulty of the nitration of other substances.

Although best known as a tool and hazard in actinide separation for nuclear reprocessing, the mix is evaluated as a Sprengel explosive. 

Although helium is inert, it is not necessarily pure. An explosion during repurification of air-contaminated helium is reported. Purification was cryogenic and involved a carbon absorber. Liquid oxygen appears to have condensed in the top of the carbon bed, forming a Sprengel explosive, which duly exploded (safety problems were one...
