p-Phenylenediamine Usage And Synthesis
Chemical PropertiesOff-white flakes
UsageA hair dye component, paraphenylenediamine, as a contact allergen for treatment of inflammatory diseases.
General DescriptionA white to purple crystalline solid (melting point 234 F) that turns purple to black in air. Flash point 309 F. Toxic by skin absorption, inhalation or ingestion. Used for production of aramid fiber, antioxidants, as a laboratory reagent, in photographic developing, and as a dye for hair and furs.
Air & Water ReactionsOxidizes on exposure to air. The finely powdered base if suspended in air poses a significant dust explosion hazard. Soluble in water. Even as a solid will spot downwind areas purple/black (Roger Patrick, DuPont Engineer).
Reactivity Profilep-Phenylenediamine is the stongest of the weak aromatic bases. p-Phenylenediamine neutralizes acids in weak exothermic reactions to form salts. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Reacts readily with oxidizing agents .
Fire HazardCombustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
