AMMONIUM 2,4,6-TRINITROPHENOLATE
Chemistry
Ammonium picrate 's Molecular formula: C6H6N4O7
Ammonium picrate 's Molar mass: 246.13 g/mol
Structure:
Density 1.719 g/cm3
Melting point: 265 °C
Solubility in water: 10 g/L (20 °C)
other names: Dunnite;Explosive D;Picratol; 2,4,6-Trinitrophenol ammonium salt;
Ammonium picrate is a salt and does not melt, so it must be loaded by compression.

History
In 1906, ammonium picrate is an explosive developed by Major Dunn.
It was used extensively by the United States Navy during World War I.
Though ammonium picrate was generally considered an insensitive substance, by 1911 the United States Army had abandoned its use in favor of other alternatives. The Navy, however, used it in armor-piercing artillery shells and projectiles, and in coastal defense.
Ammonium picrate typically did not detonate on striking heavy armor. Rather, the shell encasing it would penetrate the armor, after which the charge would be triggered by a fuse .
In 2008 caches of discarded ammonium picrate in remote locations were mistaken for rusty rocks at Cape Porcupine, Newfoundland and Labrador, Canada.

Uses
Ammonium picrate is used in armor-piercing shells as a bursting charge.
Production
Ammonium picrate (explosive D) is manufactured by the neutralization of a hot aqueous solution of picric acid (2,4,6-trinitrophenol) with aqueous ammonia.
Consensus Reports
Reported in EPA TSCA Inventory.
Safety Profile
An allergen. Moderately irritating to skin, eyes, and mucous membranes. Moderately flammable by spontaneous chemical reaction. A powerful oxidizer that reacts vigorously with reducing materials. Dangerous explosive when shocked or heated. The presence of trace metals increases its heat sensitivity. See PICRIC ACID, NITRATES, and EXPLOSIVES, HIGH. When heated to decomposition it emits highly toxic fumes of NOx.
