2,4,6-ТРИНИТРОФЕНОЛАТ АММОНИЯ

Описание

Ammonium picrate is a nitro hydrocarbon derivative. It is composed of yellow crystals with not less than 10% water by mass. Ammonium picrate is highly explosive when dry and a flammable solid when wet, and is slightly soluble in water. The four-digit UN identification number for ammonium picrate with not less than 10% water is 1310. The primary uses are in pyrotechnics and explosives.

Химические свойства

Ammonium picrate is a bright yellow crystalline solid, which turns red if contaminated.

Использование

In explosives, fireworks, rocket propellants.

Общее описание

A yellow crystalline solid. Produces toxic oxides of nitrogen during decomposition . Easily ignited and burns vigorously. May explode under prolonged exposure to fire or heat. The primary hazard is the blast effect of instantaneous explosion and not from flying projectiles and fragments.

Профиль реактивности

AMMONIUM PICRATE is a high explosive when dry [Hawley]. Mixing with water greatly reduces its sensitivity to shock, friction and heat. Traces of metallic picrates may significantly lower the temperature at which this mixture will explode (Military Explosives p. 96). Self-reactive.

Опасность

A high explosive when dry, flammable when wet.

Угроза здоровью

Fire may produce irritating, corrosive and/or toxic gases.

Пожароопасность

MAY EXPLODE AND THROW FRAGMENTS 1600 meters (1 MILE) OR MORE IF FIRE REACHES CARGO.

Профиль безопасности

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.
