  • Does 6PPD ozonation pose environmental risks?
  • 6PPD, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (TP), 6PPD-quinone (6PPDQ), during exposure to gas-phase ozone. Important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of TPs from 6PPD ozonation.
  • Does 6PPD prevent oxidation?
  • 6PPD, a globally used amine antioxidant agent added during manufacture of tires, can prevent oxidation of the final rubber products . By serving as an additive in the tires, 6PPD consumes the alkoxy radicals generated by frictional heat to prevent the rubber product from oxidizing .
  • Are substituted P-phenylenediamines effective antioxidants?
  • The substituted p-phenylenediamines (PPDs) represent a suite of effective antioxidants broadly applied in rubber industries. However, knowledge of their environmental occurrences and fate remains e...
  • What is the antioxidation reaction mechanism of 6PPD derivatives?
  • Toxicity analysis of antioxidation by-products of 6PPD derivatives The antioxidation reaction mechanism of amine antioxidants is mainly that the NH (active hydrogen) bond was broken to generate ROOH or ROH by oxygen-containing free radicals (e.g., ROO· and RO·) attack, leading to create thermal oxygen that delays rubber aging behavior , .
