  • Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
  • Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
  • What are the TPS of rubber antioxidants?
  • The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
  • Which PPD-Q compounds are found in tire rubber granules?
  • Among the various PPD-Q compounds identified in tire rubber granules (12 μg/g), rubber crumbles (0.3–25 μg/g), and recycled rubber door mats (11–26 μg/g), 6PPD-Q stands out as the most prevalent (Zhao et al., 2023b). Research indicates that sunlight not only catalyzes the formation of 6PPD-Q in TRWPs but also accelerates its breakdown.
  • Is pyrolysis a standalone solution for 6PPD decontamination and EOL tire upcycling?
  • This indicates that pyrolysis is not a standalone solution for 6PPD decontamination and EOL tire upcycling, and solvent extraction is essential for isolating this chemical. 6PPD can be catalytically converted to value-added products, such as cyclohexylamine, using a conventional Pd/C catalyst under hydrogen pressure.
