  • 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.
  • 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 most effective anti-oxidant?
  • Specifically, L-AP, L-AA, 3,5-DTBA, and DTT increased the recovery to over 60%, with L-AA demonstrating the most significant effect. L-AA is widely recognized as a low-cost and potent antioxidant that captures free radicals such as 1 O 2 , . Consequently, L-AA was selected as the protective agent.
  • Can antioxidant protection be used to detect PPDS and TPS?
  • An efficient and stable method for the detection of PPDs and their TPs was developed. Oxidative degradation is the main cause of low extraction efficiency of PPDs and some TPs. Combined strong antioxidant protection for stable extraction PPDs and their TPs was first proposed.
