amine-functionalized lignin as an eco-friendly antioxidant,herein, as an alternative material of 6ppd, we newly introduce eco-friendly amine-functionalized lignin (al) to be incorporated in rubber, which can provide excellent combinatorial antiaging properties of thermal stability and ozone/fatigue resistances through radical scavenging effect.
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.

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.
Rubber Antiageing Antiage Antioxidant 4020/6PPD price,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.

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. although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance.
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.

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.
rubber antioxidants and their transformation products,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 .
- 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.
- 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 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.
- Does 6ppdqi react with ozone?
- Initially, 6PPD undergoes ozonation, resulting in the production of benzoquinone imine, also known as N- (4- (1,3-dimethylbutyl)imino)-2,5-cyclohexadiene-1-ylidene (6PPDQI). However, 6PPDQI is unstable and reacts with ozone to form 6PPDQI-OH.
