Dead on the field of science
Other liquids have been the subject of study. Among them
hydrazoic acid is of particular interest. [Ar. 1926] R[egnald
] A[rthur[ Joyner measured the detonation velocity of propagation
of explosion in gradually increasing concentrations of hydrazoic
acid in water solution. He found that solutions containing only 17
per cent. Of HN3 would burn at about 14 cm. per. sec.
Concentrations of 50 to 60 per cent. Burned at very high speeds,
and concentrations above 65 per cent. detonated. Even when the
solution contained 20 per cent. water, detonation velocities of
8,500 m./sec. were recorded. Unfortunately, Joyner was killed
while carrying out these experiments and higher concentrations
were never investigated.

Azoimide is a clear, colorless, mobile liquid, which boils without decomposition
at 37o. It is endowed with the same intolerable odor as the solution. Its most
characteristic property, however, is its frightful explodes in a most erratic
manner-- sometimes without, the least apparent provocation at the ordinary
temperature. Its distillation is an operation attended by great danger. Prof.
Curtius and his assistant have succeeded, as above described, in isolating it and
determining its boiling point several times; but upon other occasions, under
apparently the same conditions, the experiment has ended with a disastrous
explosion. When suddenly heated or touched with a hot body, it always
explodes. The explosion is accompanied by an intensely vivid blue flame. The
damage wrought by the explosion of very minute quantities is most surprising.
The thousandth part of a gramme, placed upon an iron plate and touched by a
hot glass rod, is sufficient to produce a loud detonation, and considerably distort
the iron plate. The twentieth part of a gramme was found sufficient to
completely pulverize Hofmann "density" apparatus, when an attempt was made
to determine it vapor density in the Torricellian vacuum at the ordinary
temperature. Upon another occasion, seven-tenths of a gramme, contained in a
closed glass tube, upon removal from the freezing mixture in which it had been
immersed exploded with such an immense force as to shatter every piece of
glass apparatus in the laboratory. It was upon this occasion that Prof. Curtius's
assistant [Dr. Radenhausen] was so seriously injured as to cause the temporary
abandonment of the work. The aqueous solution is almost as explosive as the
anhydrous liquid, the explosion of two cubic centimeters of a 27 per cent.
solution upon one occasion shattering the glass tube into dust so fine that Prof.
Curtius, who was attempting to seal it, escaped uninjured.
