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. Particulate-phase N,N'-diphenyl-p-phenylenediamine will be

1. Introduction. N,N′-diphenyl-p-phenylenediamine (DPPD; CAS: 74-31-7), a gray or dark gray powder, is used as a polymerization inhibitor and antioxidant ().The antioxidative activity of DPPD is implemented by the donation of a hydrogen to a radical derivative and breaking the autocatalytic cycle (Chemicalland21, 2012).DPPD is widely used in rubber, oils, and feedstuffs, especially for tires

Curiously, above 2000 ppm, BHA displayed no effect on the stability of the esters, yielding IT values that were practically identical to those of the original sample, with no added antioxidants. By analyzing Figure 1,one notes that, up to the level of 1500 ppm, BHT and BHA were the antioxidants that provided the greatest increases in IT, with the most noteworthy of the two being BHT.
natural rubber of H. brasiliensis (99% of the world market) and guayule rubber of Parthenium argentatum (1% of the world market) are produced commercially (52). Latex of Hevea plants contains about 30% poly(cis-1,4-isoprene) and is har-vested by a “tapping” procedure after the bark of the plants is notched diagonally, which yields 100 to 200 ml latex resin within 3 h.
