end-of-life tire decontamination from 6ppd and upcycling,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, or n-1,3-dimethylbutyl-n’-phenyl-p-phenylenediamine, is a synthetic rubber antioxidant widely used in the tire and rubber industry. it provides protection against degradation caused by heat, oxygen, and flex-cracking. 6ppd acts as a stabilizer and antiozonant, preventing the formation of harmful free radicals and extending the service life of rubber products.

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 antioxidants and their transformation products mdpi
antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber.

a nation-wide study for the occurrence of ppd antioxidants and 6ppd,in conclusion, the three rubber antioxidants have gradually phase-out (zhu et al., 2016; matsumoto et al., 2013) and relatively low levels of cppd, ippd and 77pd were observed in road dust. the concentrations of σppds in urban trunk road dust samples were in the ranges of 7.90–727 ng/g, with a median of 68.3 ng/g.

rubber antioxidant ippd(4010) is dissolves in the oil class, the acetone, the benzene, the carbon tetrachloride carbon, the carbon bisulfide, and the ethyl alcohol, difficult to dissolve in the gasoline. if it is exposes under the air and the sunlight will change.
environmental chemical rubber antioxidants,amine antioxidant is the most common rubber antioxidant, which was produced as early as the 1970s and widely used in the rubber industry. typical amine antioxidants include diaryl-secondary amine, acetone-amine condensation product, p-phenylenediamine, and aldehyde-amine condensation product antioxidants [ 17 ].
- What are the TPS of rubber antioxidants?
- The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
- Which rubber antioxidants are used in China?
- Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
- Are PPD antioxidants effective in reducing tire wear?
- It is reported that PPD antioxidants have been largely applied in commercial vehicle tire formulations (1–4% by mass). (11,35) Fomba et al. found a larger contribution of tire wear to the atmosphere particulates at a traffic-dominated site (2.0–2.9%) compared to an urban background (1.7–2.1%).
- Are rubber antioxidants toxic?
- Recent advances in the toxicity issue of rubber antioxidant With the increasing popularity of automobiles, tire wear particles, generated from tire material during use on roads, would ultimately enter the eco-system, such as soil, aquatic environment, etc .
