  • 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...
  • Is 6PPD a toxicity hazard?
  • However, this same property facilitates the transfer of 6PPD and its oxidation products into the environment as tire-wear debris. The 6PPD-quinone (6PPD-Q, CAS RN: 2754428-18-5) is of particular and increasing concern, due to its toxicity to fish.
  • What is the difference between 6PPD and real retinoids?
  • Unlike the neat 6PPD, the real extract produced approximately 60% liquid (soluble in methanol) and 40% solid products. The only product made was 2,2,4-trimethyl-1,2,3,4-tetrahydroquinoline, a starting material for the synthesis of retinoids 37. See Supplementary Fig. 21 for more details.
  • 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.
