tire manufacturers rubber antioxidant 6ppd
washington d.c.—the push to find an alternative to the tire antidegradant 6ppd—an additive that is critical to consumer safety but can transform into an offshoot chemical that is fatal to some fish species—continues for the u.s. tire manufacturers association.
environmental impact of tire wear: the 6ppd-q issue trc,the compound 6ppd (short for 1,4-benzenediamine, n-(1,3-dimethylbutyl)- 21 n’-phenyl-; cas #793-24-8) is an antioxidant and antiozonant that prevents degradation of rubber compounds caused by their exposure to oxygen, ozone and temperature fluctuations. 6ppd is widely used in the tire manufacturing industry to help tires resist degradation and cracking and promote product longevity and.
- Can 6PPD be removed from end-of-life tires?
- We introduce a decontamination strategy that removes 6PPD from end-of-life tires before it enters the broader ecosystem. We demonstrate the catalytic upgrade of 6PPD to safe chemicals and the valorization of crumb rubber to aromatics and carbon black using microwave-assisted pyrolysis. You have full access to this article via your institution.
- Why is acetone better than 6PPD?
- Acetone’s lower boiling point (56 °C) compared with 6PPD (260 °C) makes solvent recovery much less energy intensive. Although acetone can readily dissolve many classes of molecules 25, it does not degrade the cross-linked rubber phase. This is crucial for producing a 6PPD-free crumb rubber product that is safe for various applications.
- Can 6PPD be recycled?
- We demonstrate the catalytic upgrade of 6PPD to safe chemicals and the valorization of crumb rubber to aromatics and carbon black using microwave-assisted pyrolysis. Upcycling end-of-life tire waste is complex due to the recalcitrant nature of the toxic legacy additive, 6PPD.
- Does acetone remove 6PPD from waste rubber?
- A parity plot of the measured extraction efficiency versus the calculated 6PPD solubility (Fig. 2e) corroborates that solubility is a crucial determinant of the solvent’s ability to remove 6PPD from waste rubber and confirms that acetone is one of the best solvents while being inexpensive and non-toxic.
