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.

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.

to examine the effects of o 3 on 6ppd transformation and tp formation in tire rubber matrices, twps were exposed (6 h) to o 3 (360 ± 12 ppbv) or zero-grade air in triplicate glass columns (1 ×.
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.
- 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.
- 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 pyrolysis irradiation decontaminate crumb rubber?
- Volumetric heating of the carbon-black-based particles indicates uniform heating during microwave irradiation. The direct pyrolysis of crumb rubber, however, is not an effective decontamination strategy as 6PPD emerges in the pyrolysis oil product. We then turn to microwave-assisted solvent extraction to isolate 6PPD from the feedstock.
- 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.
