transformation product formation upon heterogeneous ozonation,here, we investigated tp formation occurring during heterogeneous reaction of gas-phase ozone with the common tire rubber antioxidant 6ppd (n-(1,3-dimethylbutyl)N'-phenyl-p-phenylenediamine); exposures included both pure compound and twp rubbers. oxidative transformation occurred during ozonation (∼360 ppbv), with up to 81% of 6ppd mass
Rubber antioxidant 6PPD, or N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine, is a widely used chemical compound in the rubber industry, particularly known for its effectiveness in preventing oxidative degradation of rubber products.
transformation products of tire rubber antioxidant 6ppd for sale
6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
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.

this study revealed that sunlight-induced transformation of 6ppd could be an important origin of 6ppd-q in aquatic environments, providing significant insights to the potentially underestimated ecological risks of 6ppd.
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.
rubber antioxidants and their transformation products
recently, it was reported that the rubber antioxidant n-(1,3-dimethylbutyl)N'-phenyl-p-phenylenediamine (6ppd or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (twps).
a tire industry perspective on 6ppd replacement: the challenge,to act like 6ppd, a drop-in substitute must: function as antiozonant and antioxidant to help prevent the degradation and cracking of rubber compounds (unsaturated elastomers) by protecting against ozone attack, oxidation, and heat aging.
rubber antioxidants and chemical 6ppd
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.
environmental impact of tire wear: the 6ppd-q Rubber Antioxidant,The compound 6ppd (1,4-phenylenediamine, short for n-(1,3-dimethylbutyl)-21 n'-phenyl-; CAS #793-24-8) is an antioxidant and antiozonant that prevents rubber compounds from degrading due to exposure to oxygen, ozone, and temperature fluctuations. 6ppd is widely used in the tire manufacturing industry to help tires resist degradation..
- 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.
- Does 6PPD react with tire wear particles?
- In another study, a primary molar yield (per mole 6PPD consumed) of approximately 9.7 % was observed for 6PPD-Q formation from pure 6PPD and about 0.95 % from 6PPD within tire wear particles, suggesting that a substantial mass fraction of 6PPD will ultimately react to form 6PPD-Q (Hu et al., 2022).
- Is 6PPD a common compound in tire tread particles leachate?
- The study revealed that 6PPD was among the most prevalent compounds in the leachate of micron-sized tire tread particles, while its presence was less pronounced in centimeter-sized tire tread particles leachate.
- Can 6PPD be removed from end-of-life tires?
- We introduce a decontamination strategy that removes 6PPD from end-of-life tires before it enters the broader ecosystem. We demonstrate the catalytic upgrade of 6PPD to safe chemicals and the valorization of crumb rubber to aromatics and carbon black using microwave-assisted pyrolysis.
