new evidence of rubber-derived quinones in water, air for sale,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.
6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.
environmental profiles, hazard identification for sale
transformation of 6ppd and 6ppd-q in various environmental compartments. the primary sources of 6ppd and 6ppd-q in the environment are tire and road wear particles. in the atmosphere, 6ppd undergoes a reaction with ozone to form 6ppd-q under conditions such as light and high temperature.
computational studies of rubber ozonation explain the,abstract: the discovery that the commercial rubber anti-degradant 6ppd reacts with ozone (o3) to produce a highly toxic quinone (6ppd) spurred a significant research efort into nontoxic alternatives. this work has been hampered by lack of a detailed understanding of the mechanism of protection that 6ppd afords rubber compounds against ozone.
6ppd rubber antioxidant: characteristics, applications
6ppd (n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a highly effective rubber antioxidant with notable characteristics, including excellent heat resistance, anti-flex cracking properties, and compatibility with various rubber types.
environmental fate of tire-rubber related pollutants 6ppd,To improve tire durability, the antioxidant n-(1,3-dimethylbutyl)-n-phenyl-p-phenylenediamine (6PPD) is used in rubber, but when exposed to oxidants such as ozone (O3), it is converted into toxic 6PPD quinone (6PPD-Q), causing ecological problems. this review synthesizes the existing data to assess the transformation, bioavailability, and
mass spectrometry analysis of a ubiquitous tire rubber
its transformation product, 6ppd-quinone, has been identified as a potent toxicant responsible for the acute mortality of coho salmon in pacific northwest during storm events, a phenomenon called “urban runoff mortality syndrome” that persists for decades.
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
new research indicates higher 6ppd migration from silica tire
hanover, germany tire antidegradants based on 6ppd migrate at a significantly higher rate from silica-reinforced rubbers than from carbon-black reinforced equivalents, new research has found.

- 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.
- 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.
- What are the data gaps in 6PPD ozonation?
- 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 conducted over 24–168 h and ozonation TPs were characterized using high-resolution mass spectrometry.
- What are the effects of 6PPD & 6ppd-q in air and dust?
- Evaluating different Impacts of 6PPD and 6PPD-Q in air and dust. The presence of 6PPD and 6PPD-Q contributes to inhalation hazards by releasing particulate matter and volatile organic compounds into the air. Inhalation of these pollutants poses risks to respiratory health and may lead to various respiratory issues upon exposure.
