  • Are 6PPD and IPPD a contaminant?
  • 6PPD and IPPD were detected in white shrimp samples collected from aquafarms. Given the high toxicity of N- (1,3-dimethylbutyl)-N’-phenyl- p -phenylenediamine (6PPD) derivatives, such as 6PPD quinone (6PPDQ) to salmon, as well as their ubiquitous presence in the environment, the contaminant of aquatic food products has drawn significant attention.
  • Why should I use 6PPD instead of ozone?
  • This can be beneficial to the tire, as ozone attacks the tire surface and blooming therefore moves the antiozonant to where it is most needed, however this also increases the leaching of IPPD into the environment. Many tire producers have moved to using 6PPD instead, as this migrates more slowly.
  • 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.
  • Why is 6PPD stable under alkaline conditions?
  • Under alkaline conditions, the molecular form of 6PPD is not easy to be excited as (*6PPD), so it is relatively stable . Moreover, the lower oxidation potential of free radicals under alkaline conditions may reduce the oxidative degradation of diphenylamine . These may account for the increased recovery of 6PPD and 4-ADPA.
