transformation products of tire rubber antioxidant 6ppd in,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. to address these data gaps, gas-phase ozonation of 6ppd was.
environmental fate of tire-rubber related pollutants 6ppd and 6ppd-q: a
abstract. to enhance tire durability, the antioxidant n- (1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) is used in rubber, but it converts into the toxic 6ppd quinone (6ppd-q) when exposed to oxidants like ozone (o 3), causing ecological concerns. this review synthesizes the existing data to assess the transformation, bioavailability.

transformation products of tire rubber antioxidant 6ppd price
recent evidence indicated the heterogeneous reaction of gas-phase ozone with the precursor of 6ppd-q, a widely adopted tire rubber antioxidant named 6ppd, thus yielding a range of tps including.
rubber antioxidants and their transformation products mdpi,antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber.

- 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.

- 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.
- Is pyrolysis a standalone solution for 6PPD decontamination and EOL tire upcycling?
- This indicates that pyrolysis is not a standalone solution for 6PPD decontamination and EOL tire upcycling, and solvent extraction is essential for isolating this chemical. 6PPD can be catalytically converted to value-added products, such as cyclohexylamine, using a conventional Pd/C catalyst under hydrogen pressure.
- 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.
