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 rubber antioxidant: characteristics, applications
6ppd is an organic compound belonging to the p-phenylenediamine class of antioxidants. it is a dark purple solid with a slight odor. chemically, it consists of n- (1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine molecules. 6ppd is known for its solubility in rubber and compatibility with various types of rubber. 2.
hot sale rubber antioxidant 6ppd for tyre/shoes,n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine quinone (6ppd-quinone) is a degradation product of 6ppd, an antioxidant widely used in rubber tires. 6ppd-quinone enters aquatic ecosystems.

p-phenylenediamines and p-phenylenediamine quinone,furthermore, zhao et al. detected 6ppd-q at high concentrations in tire wear particles (12 μg/g), rubber debris (9.8 μg/g), and door mats containing recycled tire rubber (18 μg/g), 6ppd-q (11–64 μg/g, median: 39 μg/g), and 6ppd-q was identified as the dominant ppd-q in rubber tires (zhao et al. 2023). although we found that there were.

6ppd (4020) chemical structure. chemical name : n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine cas no. : 793-24-8 as a kind of phenylene diamine rubber antioxidant, 6ppd has better compatibility with rubbers, seldom blooming, low volatility, low toxicity, excellent antioxidant, anti-ozone, anti-flex cracks ,good dispensability in sizing material and little effect on vulcanization, anti.
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.
- 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 .
- Is 6PPD a toxic oxidant?
- To enhance tire durability, the antioxidant N- (1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) is used in rubber, but it converts into the toxic 6PPD quinone (6PPD-Q) when exposed to oxidants like ozone (O 3), causing ecological concerns.
- Do Antioxidants improve the performance of rubber?
- Conclusions and Future Perspectives Antioxidants are widely used to improve the performance of rubber, and their production, especially 6PPD, is annually maintained at a high level .
- How many rubber antioxidants are produced in China?
- China is one of the main countries producing rubber antioxidants, and the production accounts for more than 70% of the total amount globally. The production of rubber antioxidants in China ranged from 365,000 to 378,000 tons during 2016–2020, showing a constant annual trend .
