first insights into 6ppd-quinone formation from 6ppd
(a) effect of irradiation wavelength on 6ppd photodegradation; (b) characteristic absorption of 6ppd at a concentration of 2 mg/l (blue curve), light transmission of filter (λ 400 nm, red curve), and emission spectrum of the 500-watt xenon lamp used in the photodegradation (black curve); (c) effects of initial ph on 6ppd photodegradation.
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.
environmental fate of tire-rubber related pollutants 6ppd
the continuous release of ppds in the environment triggers chemical reactions, resulting in the formation of other emerging pollutants and subsequent environmental contamination (zhang et al., 2024a). 6ppd is the most extensively used rubber antioxidant, reaching a production volume of 200 thousand tons in china in 2020 (zhang et al., 2022).

6ppd rubber antioxidant: characteristics, applications
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,antioxidant at 0.4−2% by weight,33 where it is designed to quickly react with ground-level o 3 to protect rubber elastomers.34,35 such reactions inevitably form other trans-formation products (tps) beyond 6ppdq during the tire rubber lifetime.21,34 for example, early studies on the antioxidant ecacy of 6ppd (e.g., lattimer et al.) proposed
antioxidant 6ppd / 4020 with factory price and good quality
6ppd is an organic chemical widely used as stabilising additive (or antidegradant) in rubbers, such as nr, sbr and br; all of which are common in vehicle tires. [1] although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance.
rubber antioxidants and their transformation products,notably, antioxidants are generally used to prevent rapid aging of rubber, which suggests a high environmental persistence of these chemicals. the study on their environmental behaviors should be strengthened, especially the environmental impacts of those beyond 6ppd in various environments, including polar regions.
- Are there alternatives to 6PPD as a rubber antioxidant?
- Nevertheless, conclusive studies identifying superior alternatives to 6PPD as a rubber antioxidant remain scarce in the current literature. Urbanization has resulted in an increase in surface runoff, a phenomenon that plays a pivotal role in the transportation of chemicals originating from tire wear into aquatic environments.
- What is the content of 6PPD in rubber?
- Typically, the content of 6-PPD in rubber materials ranges from 0.4% to 2% . During its production and use, 6-PPD can be transported to exposed surfaces and enter the environment. These antioxidants are highly reactive to ozone . 6-PPDQ is more stable than 6-PPD.
- Which phosphorus flame retardant produces the highest amount of rubber antioxidants?
- The production and consumption of rubber antioxidants have been increasing globally in recent years and are much higher than the consumption of phosphorus flame retardants . 6-PPD produces the highest amount of rubber antioxidants compared to other antioxidants .
- Why is 6PPD important?
- Globally the increasing demand for rubber tires leads to the extensive consumption of 6PPD up to millions of tons resulting in significant release of this compound from tire rubber to the environment (Rossomme et al., 2023).
