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.
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.

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.
from tread to watershed: how tire wear particle chemicals
the environmental ubiquity of tire and road wear particles (trwp) underscores the need to understand the occurrence, persistence, and environmental effects of tire-related chemicals in aquatic ecosystems. one such chemical is 6ppd-quinone (6ppd-q), a transformation product of the tire antioxidant 6ppd.

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.
screening p-phenylenediamine antioxidants, their,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.

- Which PPD-Q compounds are found in tire rubber granules?
- Among the various PPD-Q compounds identified in tire rubber granules (12 μg/g), rubber crumbles (0.3–25 μg/g), and recycled rubber door mats (11–26 μg/g), 6PPD-Q stands out as the most prevalent (Zhao et al., 2023b). Research indicates that sunlight not only catalyzes the formation of 6PPD-Q in TRWPs but also accelerates its breakdown.
- What influences the environmental distribution of organic chemicals 6PPD & 6ppd-q?
- The environmental distribution, fate, and processes of organic chemicals 6PPD and 6PPD-Q are significantly influenced by various meteorological elements, including temperature, precipitation, and humidity.
- Does 6ppd-q affect lipid metabolism in Caenorhabditis elegans?
- The compromised intestinal barrier function caused by 6PPD-Q was associated with the down-regulation of the intestinal barrier gene acs-22 and the induction of intestinal stress responses (Hua et al., 2023a). Moreover, 6PPD-Q impacted lipid metabolism in Caenorhabditis elegans.
