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 (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.
6ppd: its role in tire manufacturing and environmental impact
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.
recent progress in the rubber antioxidants price,separately, 4-(dimethyl-butyl amino)diphenylamine (6ppd), another widely used antioxidant in the rubber industry, a recent study reported that the 6ppd (or already converted 6ppd-quinone) released from the tires reacts to form 6ppd-quinone, which is toxic to.
uptake and biotransformation of the tire rubber-derived contaminants 6
n-(1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) is a widely used antioxidant in tire rubber known to enter the aquatic environment via road runoff. the associated transformation product (tp) 6ppd quinone (6ppdq) causes extreme acute toxicity in some fish species (e.g., coho salmon). to interpret the species-specific toxicity, information about biotransformation products of 6.
environmental impact of tire wear: the 6ppd-q issue trc,the compound 6ppd (short for 1,4-benzenediamine, n-(1,3-dimethylbutyl)- 21 n’-phenyl-; cas #793-24-8) is an antioxidant and antiozonant that prevents degradation of rubber compounds caused by their exposure to oxygen, ozone and temperature fluctuations
tire manufacturers association and u.s. geological survey partner
it also provides critical needs for endurance and product safety. 6ppd was first developed in the 1960s and has been widely used in motor vehicle tires since the 1970s. this ustma and usgs collaboration marks another important step in the continuing efforts by tire manufacturers to look for possible 6ppd replacements.
a review of n-(1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd,1. introduction n-(1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) is an antiozonant and antioxidant which is predominantly used as an additive in synthetic rubber industries, especially in tire products. 6ppd is mainly added to tire preparation formulations at a mass ratio of 0.4–2% to prevent the bending cracking, thermal degradation, and ozone cracking of the rubber materials [].
toxicological effects of 6ppd and 6ppd quinone in zebrafish larvae
n-(1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) is the most widely used antioxidant in automobile tyres and many rubber products. we investigated the impact of 6ppd and 6ppd quinone on acute toxicity, morphology, swimming behaviour, heart rate, and oxygen consumption in zebrafish larvae.
screening p-phenylenediamine antioxidants, their transformation,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.
- 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.
- Why is 6ppd-q important?
- 6PPD-Q in human samples highlight the need for further research on public health. N- (1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) is commonly used in rubber compounds as antioxidants to protect against degradation from heat, oxygen, and ozone exposure.
- What are the primary sources of 6PPD & 6ppd-q?
- 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. In the pedosphere, the transformation of 6PPD-Q primarily occurs through heterogeneous iron reduction by microorganisms.
- Which compound has the highest antioxidant levels in Guangzhou & Taiyuan?
- The same trend was also observed in its parent compound, 6PPD, which showed the highest proportion among these antioxidants in Guangzhou (46%), with a median level of 1820 pg/m 3, while that in Taiyuan was only 20%, with a median value of 81.0 pg/m 3 ( Table 1 ).
