  • What is the most common PPD antioxidant?
  • Among the PPDs, N - (1,3-dimethybutyl)- N’ -phenyl- p -phenylenediamine (6PPD) stand as the preeminent tire antioxidant, reigning as the most prevalent PPD antioxidant globally. In China, the production of 6PPD is about 200,000 tones in 2020, accounting for approximately 54% of the global production .
  • 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.
  • Are PPD antioxidants toxic?
  • An increasing number of studies have focused on the toxicity of these PPD antioxidants. (8−10,15,33) According to the European Chemical Agency, several of them were labeled as very toxic to aquatic life with long-lasting effects and harmful if swallowed and may cause an allergic skin reaction.
  • Do p-phenylenediamine antioxidants oxidize during pretreatment?
  • There are relatively few reports on the content of p-Phenylenediamine antioxidants (PPDs) and their transformed products (TPs) in aquatic products. Quantifying PPDs, PPDQs, and other TPs is challenging owing to their tendency to oxidize and decompose during pretreatment, especially in organisms.
