  • Are p phenylenediamine (PPD) antioxidants in recycled tire rubber products toxic?
  • Recently, roadway releases of N, N ′-substituted p -phenylenediamine (PPD) antioxidants and their transformation products (TPs) received significant attention due to the highly toxic 6PPD-quinone. However, the occurrence of PPDs and TPs in recycled tire rubber products remains uncharacterized.
  • Is 6PPD a good anti-ozonant?
  • However, 6PPD has emerged as the anti-ozonant of choice by the industry due to a wide variety of factors, including migration time, molecular weight, melting point, and compatibility with rubber formulations. Get the latest news and updates.
  • 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.
