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: its role in tire manufacturing and environmental impact,published oct 19, 2024. 6ppd, or n- (1,3-dimethylbutyl)-n’-phenyl-p-phenylenediamine, is a chemical compound widely used in tire manufacturing. its primary function as an antioxidant enhances tire durability by preventing degradation from environmental factors like heat, oxygen, and ozone. however, recent studies have raised concerns about.
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.
a nation-wide study for the occurrence of 6ppd antioxidants,n,n′-substituted p-phenylenediamines (ppds) are widely used antioxidants in rubber tires, which could be released and accumulated in road dusts with rubber tires wear.. as ozonation product of n-(1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd), 6ppd-quinone (6ppd-q) exhibited higher toxicity to coho salm
p-phenylenediamines and p-phenylenediamine quinone
according to data from the china rubber industry association, 6ppd and ippd have the highest production volumes among all rubber antioxidants (approximately 60% of the total), which explains the high contributions of 6ppd and ippd in the dust samples (china rubber industry association, 2023). in residential environments, ippd, dnpd, and 6ppd-q.
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.
environmental rubber antioxidant 6ppd
the parent chemical was not detected in seven bile samples and two metabolites, monohydroxy-6ppd-q (oh-6ppd-q) and 6ppd-q-o-glucuronide (6ppd-q-o-gluc), were found; it appears that 6ppd-q-o-gluc abundance was driven mostly by exposure concentration and could therefore be considered a biomarker of exposure, while the abundance of oh-6ppd-q.
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.
