1,4-DIAMINONAPHTHALENE Usage And Synthesis

General Description

Dark green to black crystalline solid.

Air & Water Reactions

1,4-DIAMINONAPHTHALENE may be sensitive to prolonged exposure to air. Insoluble in water.

Reactivity Profile

1,4-DIAMINONAPHTHALENE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Fire Hazard

Flash point data for 1,4-DIAMINONAPHTHALENE are not available; however, 1,4-DIAMINONAPHTHALENE is probably combustible.
