  • Can TMQ be used as a tire antioxidant?
  • This study aimed to design eco-friendly derivatives of 2,2,4-trimethyl-1,2-dihydroquinoline (TMQ) with increased antioxidant activity to use as tire antioxidants. Initially, seventy highly efficient derivatives of TMQ were designed by hydroxylation modifications at multiple sites.
  • Which rubber antioxidants are used in China?
  • Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
  • Do rubber tires need antioxidants?
  • Antioxidants are indispensable functional additives used in rubber tires to delay aging and extend their service life (Kirschweng et al. 2017 ). Six common types of tire antioxidants include amines, polyphenols, vitamin E, sulfurous, phosphite, and other compounds of essential vitamins (Chen et al. 2008 ).
  • Which hydroxyl derivatives of TMQ have the lowest toxicity risk?
  • TMQ-6 and TMQ-48 are the hydroxyl derivatives of TMQ, with the lowest toxicity risk and the highest antioxidant activity among all the hydroxyl derivatives considered in the study. These results provide guidelines and support for future efforts toward designing highly efficient and eco-friendly tire antioxidants.
