AZOXYBENZENE Chemical Properties,Uses,Production
Chemical Properties
ORANGE-YELLOW TO ORANGE CRYSTALS
Uses
Intermediate in organic synthesis.
General Description
Bright yellow crystals or yellowish-brown solid.
Air & Water Reactions
Dust may form an explosive mixture in air. Insoluble in water.
Reactivity Profile
AZOXYBENZENE is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.
Fire Hazard
Flash point data for AZOXYBENZENE are not available; however, AZOXYBENZENE is probably combustible.
Safety Profile
Poison by subcutaneous route. Moderately toxic by ingestion, skin contact, and other routes. A skin and eye irritant. Mutation data reported. Combustible. When heated to decomposition it emits toxic fumes of NOx.
Purification Methods
Crystallise azobenzene from EtOH or MeOH, and dry it for 4hours at 25o/10-3mm. Sublime it before use. [Bigelow & Palm Org Synth Coll Vol II 57 1943, Beilstein 16 II 326.]
