During the first World War the Germans used a mixture of
tnnitroanisol and hexanitrodiphenyl sulfide m bombs 71
Tnnitiophcnetol or ethyl picrate, mp 78°, is prepared by the
same methods as tnnitroanisol The explosive properties of the
two substances have been studied by Desparmets and Cahnaud,
and by Desvergnes, 72 who has reported the results of the earlier
workers together with data of his own and discussions of methods
of manufacture and of the explosive properties of mixtures with
picric acid, ammonium nitrate, etc Drop test with a 5-kilogram
weight were as follows.
HEIGHT OF DROP, CENTIMETERS PER CENT EXPLOSION
Picric acid 30 50
Trmitroanisol 100 20
Tnnitroanisol 110 30
Tnnitrophenetol 100 10
Tnnitrophenetol 110 10
Velocities of detonation (densities not reported) were tnnitroanisol
7640 meters per second, tnnitrophenetol 6880, and, for
comparison, TNT 6880 meters per second Pellets of the compressed
explosives fired in the manometnc bomb gave the results
tabulated below.
