sunlight-induced transformation of tire rubber antioxidant n-(1,3
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. doi: 10.1021/acs.estlett.3c00499 corpus id: 260939111.
end-of-life tire decontamination from 6ppd and upcycling,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.
screening p-phenylenediamine antioxidants, their transformation
recently, roadway releases of n,n′-substituted p-phenylenediamine (ppd) antioxidants and their transformation products (tps) received significant attention due to the highly toxic 6ppd-quinone. however, the occurrence of ppds and tps in recycled tire rubber products remains uncharacterized. here, we analyzed tire wear particles (twps), recycled rubber doormats, and turf-field crumb rubbers.

occurrences of tire rubber-derived contaminants in cold-climate urban,recent findings that 2-anilo-5-[(4-methylpentan-2-yl)amino]cyclohexa-2,5-diene-1,4-dione (6ppd-quinone), the transformation product of a common tire rubber antioxidant, is acutely toxic in stormwater-impacted streams has highlighted the need for a better understanding of contaminants in urban runoff. this study represents one of the first reports of 6ppd-quinone and other tire rubber-derived.
environmental chemical rubber antioxidants
2.1. amine antioxidants amine antioxidant is the most common rubber antioxidant, which was produced as early as the 1970s and widely used in the rubber industry. typical amine antioxidants include diaryl-secondary amine, acetone-amine condensation product, p-phenylenediamine, and aldehyde-amine condensation product antioxidants [].
recent progress in the rubber antioxidants price,in this review, we summarized the recent advances in rubber antioxidants over the last 10 years and offered some perspectives to outline the challenges and future research directions for the rubber antioxidants. 2. brief introduction of the oxidation process and oxidation mechanism of the rubbers.
- What are the future trends of rubber antioxidants?
- The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
- Does a sustained release of EAB improve anti-oxidative capacity of rubber composites?
- Moreover, the retention of EAB for SBR/Loaded HNTs is about 50% higher than for SBR/HNTs and CDs after the thermo-aging testing, demonstrating the sustained release of CDs from HNTs could enhance the anti-oxidative capacity of the rubber composites.
- Can a new decontamination strategy be used for recycling end-of-life tire waste?
- Upcycling end-of-life tire waste is complex due to the recalcitrant nature of the toxic legacy additive, 6PPD. Here the authors present a new decontamination strategy that can isolate 6PPD, convert it to safe and valuable products, and valorize end-of-life tire waste.
- 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.
