    N,N'-Diphenyl-p-phenylenediamine | C18H16N2

    N,N'-Diphenyl-p-phenylenediamine's production and use as an antioxidant in rubbers may result in its release to the environment through various waste streams. If released to air, a vapor pressure of 6.35X10-9 mm Hg at 25 °C indicates N,N'-diphenyl-p-phenylenediamine will exist solely in the particulate phase in the ambient atmosphere.
