N,N-Diphenyl-p-phenylenediamine may react with oxidizing materials . 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.
Air & Water Reactions
Insoluble in water.
Crystallise the diamine from EtOH, chlorobenzene/pet ether or *benzene. It has also been crystallised from aniline, then extracted three times with absolute EtOH. [Beilstein 13 H 80.]
Gray or dark gray powder or flakes.
N,N-Diphenyl-p-phenylenediamine is combustible. N,N-Diphenyl-p-phenylenediamine may form explosive dust-air mixtures.
Polymerization inhibitor. Antioxidant for rubber, petroleum oils, feedstuffs.
A rubber accelerant, formerly contained in “blackrubber mix.” The most frequent occupational categories are in the metal industry, homemakers, health services and laboratories, and the building industry.
ChEBI: An N-substituted diamine that is 1,4-phenylenediamine in which one hydrogen from each amino group is replaced by a phenyl group.
