  • Is 6PPD a toxic oxidant?
  • To enhance tire durability, the antioxidant N- (1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) is used in rubber, but it converts into the toxic 6PPD quinone (6PPD-Q) when exposed to oxidants like ozone (O 3), causing ecological concerns.
  • Is 6PPD in tires a priority product?
  • DTSC designates 6PPD in tires as a Priority Product and USTMA expands its consortium to 32 tire manufacturers from around the world to prepare a Preliminary (Stage 1) Alternatives Analysis (AA) to identify and evaluate potential alternatives to 6PPD in tires. Individual consortium members submitted the report to DTSC to meet compliance deadline.
  • What solvent is used to remove 6PPD from EOL tires?
  • Through batch extraction analysis and computational calculations, acetone is the best suited solvent for 6PPD removal from EOL tires of those tested. Furthermore, the batch extraction kinetics follow a first-order profile.
  • Can 6PPD be removed from end-of-life tires?
  • We introduce a decontamination strategy that removes 6PPD from end-of-life tires before it enters the broader ecosystem. We demonstrate the catalytic upgrade of 6PPD to safe chemicals and the valorization of crumb rubber to aromatics and carbon black using microwave-assisted pyrolysis.
