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.

rubber antioxidant 6ppd 4020 rubber antioxidant 4020(6ppd) chemical name n-(1,3-dimethyl-buty)-n'-phenyl-p-phenylenediamine molecular formula c18h24n2 cas no. 793-24-8 specification.read more as one of the most professional rubber antioxidant 6ppd manufacturers in china, we're featured by quality products and good service.

hot sale rubber antioxidant 6ppd for tyre/shoes

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.

untargeted metabolomic analysis reveals a time-course hepatic,keywords: 6ppd; untargeted metabolomics; time course; liver metabolism disorder; rat 1 introduction during tire production, additives such as vulcanizing agents, accelerators, and antioxidants are added to enhance the performance and extend the service life of rubber products (sommer et al., 2018).

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.

hot sale rubber antioxidant 6ppd for tyre/shoes,n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine quinone (6ppd-quinone) is a degradation product of 6ppd, an antioxidant widely used in rubber tires. 6ppd-quinone enters aquatic ecosystems.

a nation-wide study for the occurrence of 6ppd antioxidants

road dust is the main source of rubber-derived ppds and 6ppd-q and closely related to human health. the daily intakes of 6ppds and 6ppd-q by dermal absorption and ingestion from road dust were estimated for adults and children based on the concentrations of target compounds measured in urban trunk road dust in the present study. as shown in fig. s6.

transformation products of tire rubber antioxidant 6ppd in,ples.28−32 6ppd is ubiquitously used in tire rubbers as an antioxidant at 0.4−2% by weight,33 where it is designed to quickly react with ground-level o 3 to protect rubber elastomers.34,35 such reactions inevitably form other trans-formation products (tps) beyond 6ppdq during the tire rubber lifetime.21,34 for example, early studies on the

environmental rubber antioxidant 6ppd

n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd) is commonly used in rubber compounds as antioxidants to protect against degradation from heat, oxygen, and ozone exposure. this practice extends the lifespan of rubber products, including tires, by preventing cracking, aging, and deterioration.

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).
