General Description
Dark reddish-yellow leaflets or orange powder. Slight odor.
Reactivity Profile
C.I. SOLVENT YELLOW 14(842-07-9) 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. This chemical is incompatible with strong oxidizing agents and strong acids .
Air & Water Reactions
Azo dyes can be explosive when suspended in air at certain concentrations. Insoluble in water.
Fire Hazard
Flash point data for this chemical are not available; however, C.I. SOLVENT YELLOW 14 is probably combustible.
