diphenylamine usage and synthesis
chemical properties white crystals or powder
uses diphenylamine is an aromatic amine that was shown to exhibit antioxidant activities and is now used as an anti-scald agent.
general description light tan to brown solid with a pleasant odor. sinks in water.
air & water reactions dust may be explosive if mixed with air in critical proportions and in the presence of a source of ignition [uscg, 1999]. insoluble in water.
reactivity profile diphenylamine discolors in light. diphenylamine can react violently with hexachloromelamine and trichloromelamine. diphenylamine is incompatible with strong oxidizing agents and strong acids. diphenylamine is also incompatible with iron and silver salts. diphenylamine reacts with nitrogen oxides.
health hazard inhalation may irritate mucous membranes. overexposure, including ingestion of solid or skin contact, may cause fast pulse, hypertension, and bladder trouble. contact with dust irritates eyes.
