TETRA-NITRO-ANILINE (T. N. A.)
Tetra-nitro-aniline (briefly designated as T. N. A.) is the latest explosive to claim marked attention in the field of military explosives. The term T. N. A. is probably familiar to nearly all of the officers of the naval service, yet the scarcity of literature regarding this substance, the difficulty of finding what little there is, and the technical form in which it is written, all lead the writer to attempt to present clearly some of the more important properties and probable uses of this promising explosive.
Tetra-nitro-aniline is the strongest solid explosive compound known and, as such, must claim the greatest attention and most careful consideration from a service which has so much at stake on the quality and strength of its explosives.
It is a tetra-nitro derivative of aniline, which in turn is a simple derivative of benzene, as shown by the graphic formulas below.
