big discount rubber antioxidant 6ppd for tyre,by investigating this phenomenon, we identified a highly toxic quinone transformation product of n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd), a globally ubiquitous tire rubber antioxidant.
n-(1,3-Dimethylbutyl)-n-phenyl-p-phenylenediamine (6ppd) is a ubiquitous rubber antioxidant and antiozonant that can extend the service life of common rubber products and can be used as a thermal oxidation stabilizer for polyethylene, polypropylene and acrylic resins.
unveiling the environmental impact of tire wear particles
a prominent example of an antioxidant used in rubber is n-(1,3-dimethylbutyl)−1,4-phenylenediamine (6ppd), which readily transforms into a quinone called 6ppd-q (fig. 5 c) [56]. 6-ppd's high reactivity with ozone contributes to its transformation into 6-ppdq, a more stable compound [86].
abiotic oxidative transformation of 6-ppd and 6-ppd quinone,the reaction of solid 6-ppd with ozone gas may simulate the transformation of 6-ppd in tires and trwps, while the reaction with ozone in aqueous solution including hydrolytic reactions may simulate reactions after the release of 6-ppd from tires or from trwps into the surrounding water.
transformation products of tire rubber antioxidant 6ppd for sale
6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone.
transformation products of tire rubber antioxidant 6ppd for sale,6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.

this study revealed that sunlight-induced transformation of 6ppd could be an important origin of 6ppd-q in aquatic environments, providing significant insights to the potentially underestimated ecological risks of 6ppd.
environmental fate of tire-rubber related pollutants 6ppd,To improve tire durability, the antioxidant n-(1,3-dimethylbutyl)-n-phenyl-p-phenylenediamine (6PPD) is used in rubber, but when exposed to oxidants such as ozone (O3), it is converted into toxic 6PPD quinone (6PPD-Q), causing ecological problems.
rubber antioxidants and their transformation products
recently, it was reported that the rubber antioxidant n-(1,3-dimethylbutyl)N'-phenyl-p-phenylenediamine (6ppd or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (twps).
transformation products of tire rubber antioxidant 6ppd for sale,abstract: 6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.
- Is 6PPD a toxic oxidant?
- 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.
- Which phosphorus flame retardant produces the highest amount of rubber antioxidants?
- The production and consumption of rubber antioxidants have been increasing globally in recent years and are much higher than the consumption of phosphorus flame retardants . 6-PPD produces the highest amount of rubber antioxidants compared to other antioxidants .
- What solvent is used to remove 6PPD from EOL tires?
- Through batch extraction analysis and computational calculations, acetone is the best suited solvent for 6PPD removal from EOL tires of those tested. Furthermore, the batch extraction kinetics follow a first-order profile.
- 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.
