Safety Information
N-Phenyl-1-naphthylamine Usage And Synthesis
  • Chemical Propertiesbrown solid
  • General DescriptionWhite to slightly yellowish prisms or reddish brown crystalline powder.
  • Air & Water ReactionsMay be sensitive to prolonged exposure to air. Insoluble in water. Napthyl amines can be slowly hydrolyzed, releasing NH3 as a byproduct [N.L. Drake, Org. React. 1, (1942), 105].
  • Reactivity ProfileN-Phenyl-1-naphthylamine 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.
  • Health HazardACUTE/CHRONIC HAZARDS: When heated to decomposition N-Phenyl-1-naphthylamine emits toxic fumes.
  • Fire HazardFlash point data for N-Phenyl-1-naphthylamine are not available. N-Phenyl-1-naphthylamine is probably combustible.
  • Contact allergensPhenyl-alpha-naphthylamine is contained in some rubbers and oils as an antioxidant of the amine group. It is closely related to phenyl-beta-naphthylamine and to di-beta-naphthyl-p-phenylenediamine, but without cross-reactivity.
  • Purification MethodsCrystallise it from EtOH, pet ether or *C6H6/EtOH. Dry it under vacuum in an Abderhalden pistol. [Beilstein 12 H 1224.]
