water. The dark brown granular material may be used as such, or it
may be dissolved in hot acetone and precipitated by the addition of
a large volume of ice water to the rapidly agitated liquid, a treatment
which converts it into a brilliant yellow amorphous powder.
L. V. Clark, 57 who has made an extensive study of the physical
and explosive properties of diazodinitrophenol, reports that it has

a true density at 25°/4° of 1.63. Its appa/ent density after being
placed in a tube and tapped is only 0.27, but, when compressed
in a detonator capsule at a pressure of 3400 pounds per square
inch (239 kilograms per square centimeter), it has an apparent
density of 0.86 It is not dead-pressed by a pressure of 130,000
pounds per square inch (9139 kilograms per square centimeter).
It is soluble in nitrobenzene, acetone, aniline, pyridine, acetic
acid, strong hydrochloric acid, and nitroglycerin at ordinary temperatures.
Its solubility at 50° in 100 grams of solvent is: in
ethyl acetate 2.45 grams, in methyl alcohol 1.25 grams, in ethyl
