  • What are rubber antioxidants?
  • Antioxidants are substances that are used in rubber and plastic industries to prevent oxidation and decay of polymer materials. TMQ, also known as Polymerized 2,2,4-trimethyl-1,2-dihydroquinoline, is a widely used rubber antioxidant.
  • What is 6PPD used for?
  • Application: 6PPD is a general antioxidant and antiozonant, which is suitable for the formulations of natural rubber and synthetic rubber.
  • Does 6PPD ozonation pose environmental risks?
  • 6PPD, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (TP), 6PPD-quinone (6PPDQ), during exposure to gas-phase ozone. Important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of TPs from 6PPD ozonation.
  • Are 6PPD reactions with ozone a bioactive transformation product?
  • This article is cited by 11 publications. 6PPD reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
  • Does 6ppdq occur during ozonation of 6qdi?
  • Consistent with prior findings, 6PPDQ (C 18 H 22 N 2 O 2) was one of the major TPs in 6PPD ozonation (∼1 to 19% yield). Notably, 6PPDQ was not observed during ozonation of 6QDI (N - (1,3-dimethylbutyl)- N ′-phenyl- p -quinonediimine), indicating that 6PPDQ formation does not proceed through 6QDI or associated 6QDI TPs.
  • Is IPPD a good antioxidant?
  • IPPD is an outstanding antioxidant and antiozonant, which exhibits strong anti-ozone, anti-fatigue and anti-bending performance. It's oxidation resistance performance is better than that of quinolone and amine antioxidants. IPPD has a certain protective effect on the catalytic oxidation of copper, manganese and other variable-valent metals.
