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.
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.

rubber antioxidants and their transformation products
the oxygen consumption rate was increased rapidly in 15 min in rtgill-w1 cell after being exposed to 5–80 μg/l 6ppd-quinone, implying the tissue-specific toxicity of 6ppd-quinone . 6ppd-quinone was also observed to be highly toxic to silver salmon with an lc 50 of 0.79 ± 0.16 μg/l, which is almost three orders of magnitude lower than that.

a ubiquitous tire rubber–derived chemical induces acute,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. retrospective analysis of representative roadway runoff and stormwater-affected creeks of the u.s. west coast indicated widespread occurrence.
a nation-wide study for the occurrence of 6ppd antioxidants
in 15 cities, 6ppd contributed above 50 % to the σppds in urban trunk road dusts. as ozonation product of 6ppd antioxidant-q accounted for 4.10–76.3 % (average: 37.4 %) of the sum of ∑ppds and 6ppd-q in urban trunk road dust samples collected from 55 cities. in 46 cities, the relative contents of summed 6ppd and 6ppd-q were higher than 50 %.
6ppd chemical active antioxidant,6ppd is a common rubber antiozonant found in vehicle tires. it is mobile within the rubber and slowly migrates to the surface via blooming. on the surface it forms a "scavenger-protective film" that reacts with the ozone more quickly than the ozone can react with the rubber. this process forms aminoxyl radicals and was first thought.
- Do substituted para phenylenediamine (PPD) antioxidants affect the environment?
- Substituted para -phenylenediamine (PPD) antioxidants have been extensively used to retard oxidative degradation of tire rubber and were found to pervade multiple environmental compartments. However, there is a paucity of research on the environmental occurrences of their transformation products.
- Does 6PPD ozonation pose environmental risks?
- 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.
- Are PPD antioxidants present in all samples dominated by 6PPD and dtpd?
- PPD antioxidants, PPDQs, and other TPs were present in all samples with chemical profiles dominated by 6PPD, DTPD, DPPD, and their corresponding PPDQs.
- Which PPD is most commonly used?
- Among the various PPDs, N- (1,3-dimethylbutyl)-N’-phenyl- p -phenylenediamine (6PPD) and N-isopropyl-N’-phenyl-1,4-phenylenediamine (IPPD) are high-production-volume chemicals and the most frequently used . In 2020, China produced 200,000 tons of 6PPD, representing nearly 54% of the total production of rubber antioxidants .
