Dipicrylurea is prepared by nitration of carbanilide in one or more
stages.
Dismantling of Explosive Objects,
Especially Ammunition
A principal distinction must be made between two kinds of ammunition:
ammunition of known origin, which has been properly stored and
which has to be separated out for routine reasons (aging; replacement
by other types of ammunition), and ammunition found lying around or
acquired as booty. The latter kind of ammunition may well have been
exposed to strong corrosive agents, and its delayed action fuses may
no longer be controllable. Handling abandoned ammunition is one of
the most dangerous tasks in explosive handling and must be left to top
experts in this field (familiarity with the regulations concerning explosive
substances is NOT enough); this includes the very first attempt
to move the ammunition while still in situ. A detailed discussion of the
deactivation of abandoned ammunition is beyond the scope of this
book.
Explosive objects are classified according to the potential danger they
present. The criteria of such a classification include the nature of the
explosive object, whether or not they contain detonators or primers,
and whether or not they present a W Mass Explosion Risk. Dangerous
mechanical tasks, such as unscrewing the detonators or sawing them
off, cutting, milling, or sawing, must in any case be performed under
remote control.
Fusible explosives such as TNT and TNT mixtures may be melted out
of their containers (grenades, bombs, mines) after removal of detonators
and booster charges. The material thus obtained may be
purified and re-used for non-military purposes.
Case bonded W Composite Propellants are unloaded from their casing
by a remote controlled lathe or water gun; also W Case Bonding

Ditching Dynamite
A mixed dynamite, containing about 50% non-gelatinized nitroglycerine,
used for ditch blasting. This explosive displays a particularly
strong tendency to flash over. Usually only the first charge is initiated
by the cap. The following charges for the excavation of the “ditch” are
exploded by the effect of the first detonation (shock wave) (W Detonation,
Sympathetic Detonation).
