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.
6ppd (6ppd or n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a widely used rubber antioxidant that plays a vital role in the production of rubber products. this article aims to provide an overview of 6ppd, its characteristics, its applications in rubber product manufacturing, potential product combinations, and important considerations for commercial procurement. 1. what is 6ppd? 6ppd.

end-of-life tire decontamination from 6ppd and upcycling nature,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 found in tires. it.

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.
acute toxicity testing of pink salmon (oncorhynchus gorbuscha,the acute toxicity of 6ppd‐quinone is investigated in pink salmon alevins (sac fry), the only pacific salmon that so far has not been tested for 6ppd‐quinone sensitivity. n‐(1,3‐dimethylbutyl)‐n′‐phenyl‐p‐phenylenediamine‐quinone (6ppd‐quinone) is a widespread contaminant of emerging concern resulting from oxidation of 6ppd, which is an antidegradant substance added to.

6ppd is an organic chemical widely used as stabilising additive (or antidegradant) in rubbers, such as nr, sbr and br; all of which are common in vehicle tires. [1] although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance.
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).
