rial which composes the burnt head of the match has become thoroughly
heated, it is extinguished by shaking, and the burnt head is
then touched to the heap of nitrosoguanidme. The nitrosoguanidine
explodes with a zishmg sound and with a cloud of gray smoke, but
with no visible flash whatsoever. The place on the hand where the
nitrosoguanidme was fired will perhaps itch slightly, and the next day
will perhaps show a slight rash and peeling of the skin There is no
sensation of being burned, and the explosion is so rapid that the hand
remains steady and makes no reflex movement.
Ethylenedinitramine
Ethylenedinitramine, m p 174-176° with decomposition, is
produced when dinitroethyleneurea is refluxed with water, 26 or it

may be prepared directly, without isolating this intermediate,
by the nitration of ethyleneurea with mixed acid.
