  • Is 6PPD recalcitrant under harsh pyrolysis?
  • This demonstrates the recalcitrant nature of 6PPD under harsh pyrolysis conditions and suggests solvent extraction is necessary for its removal. The TGA curve (Supplementary Fig. 11) of 6PPD shows a maximum degradation at ~300 °C and suggests that some 6PPD in the tires may sublime into the liquid product before the rubber degrades.
  • Which GC GC is used to identify 6PPD and fatty acid products?
  • An Agilent 8890 GC connected to a 5977B GC MSD with a DB-5 column was used to identify and quantify 6PPD and fatty acid products. The COSMO-RS method was used to perform solid–liquid solubility calculations. The Amsterdam Modeling Suite COSMO-RS was used.
