General Description
Yellow crystalline solid. Mp: 76°C; bp: 315°C. Insoluble in water. Very soluble in ethyl alcohol and in diethyl ether. Toxic to aquatic organisms, may cause long-term adverse effects in the environment.
Reactivity Profile
2-NITRONAPHTHALENE is non-flammable but combustible (flash point 160°C). Dust forms explosive mixtures with air. Heating or burning releases toxic and corrosive gases. Incompatible with strong oxidizing agents. Can serve as an oxidizing agent and so react with reducing agents such as hydrides, sulfides and nitrides. Such reactions may be vigorous and may culminate in a detonation. May explode in the presence of strong bases such as sodium or potassium hydroxide even in the presence of water or organic solvents.
Safety Profile
Confirmed carcinogen
with experimental tumorigenic data.
Moderately toxic by ingestion and
intraperitoneal routes. Mutation data
reported. A sktn and lung irritant. For
explosion and disaster hazards, see
NITRATES. Combustible when exposed to
heat or flame. When heated to
decomposition it emits toxic fumes of NOx.

Purification Methods
Distil it in a vacuum and/or crystallise it from aqueous EtOH and sublime in a vacuum. The 1:1 1,3,5-trinitrobenzene complex has m 75.5o (from EtOH). [Beilstein 5 H 555, 5 III 1596, 5 IV 1675.]
