end-of-life tire decontamination from 6ppd and upcycling nature,abstract. n (1,3-dimethylbutyl)- n ′-phenyl- p-phenylenediamine (6ppd) is a ubiquitous rubber antioxidant and antiozonant that extends the lifetime of common rubber products, such as those.
ozonated 6ppd and twp samples, underscoring formation of diverse tps from this antioxidant. by screening environmental samples, nine 6ppd-derived tps were detected within roadway runoff. the data confirm that when tire rubber antioxidants react with ozone, as intended, they form and release various tps to surrounding environments.

6ppd chemical active antioxidant,6ppd is a common rubber antiozonant found in vehicle tires. it is mobile within the rubber and slowly migrates to the surface via blooming. on the surface it forms a "scavenger-protective film" that reacts with the ozone more quickly than the ozone can react with the rubber. this process forms aminoxyl radicals and was first thought.
sunlight-induced transformation of tire rubber antioxidant
semantic scholar extracted view of "sunlight-induced transformation of tire rubber antioxidant n-(1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) to 6ppd-quinone in water" by yangjian zhou et al.
environmental fate of tire-rubber related pollutants 6ppd and,the continuous release of ppds in the environment triggers chemical reactions, resulting in the formation of other emerging pollutants and subsequent environmental contamination (zhang et al., 2024a). 6ppd is the most extensively used rubber antioxidant, reaching a production volume of 200 thousand tons in china in 2020 (zhang et al., 2022).
- Are 6PPD antioxidants toxic to aquatic species?
- These results reveal unanticipated risks of 6PPD antioxidants to an aquatic species and imply toxicological relevance for dissipated tire rubber residues. Humans discharge tens of thousands of chemicals and related transformation products to water (1), most of which remain unidentified and lack rigorous toxicity information (2).
- 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.
- How does microbial Fe (III) reduction affect the formation of 6ppd-q?
- In the initial aging stage, microbial Fe (III) reduction transforms 6-PPD into 6PPD-Q (Xu et al., 2023b). Subsequently, the formation of 6PPD-Q is facilitated by environmentally persistent free radicals (EPFRs), resulting in the generation of O 2 •-, indicating the potential formation of 6PPD-Q without ozone presence (Xu et al., 2023b).
- 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.
