6ppd chemical active antioxidant,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. it is one of several antiozonants based around p-phenylenediamine.[2.
as we advance into 2024, the role of antioxidants in rubber manufacturing remains crucial. one such critical antioxidant is n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd). this article provides a comprehensive overview of 6ppd, comparing it with

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.
transformation products of tire rubber antioxidant 6ppd price
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.

curcuma longa-based green and sustainable antioxidants for biopolymers,unsaturated biopolymers (e.g., natural rubber (nr)) are highly vulnerable to thermo-oxidative degradation, which causes premature failure of nr products. as an indispensable antioxidant globally, 6ppd (n-(1,3-dimethyl butyl)-n′-phenyl-p-phenylenediamine) is employed to retard the thermo-oxidative aging of nr. unluckily, 6ppd and 6ppd-quinone (an oxidative product of 6ppd) are highly harmful.
- 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.
- Does 6ppdq occur during ozonation of 6qdi?
- Consistent with prior findings, 6PPDQ (C 18 H 22 N 2 O 2) was one of the major TPs in 6PPD ozonation (∼1 to 19% yield). Notably, 6PPDQ was not observed during ozonation of 6QDI ( N - (1,3-dimethylbutyl)- N ′-phenyl- p -quinonediimine), indicating that 6PPDQ formation does not proceed through 6QDI or associated 6QDI TPs.
- Does 6ppd-q have a higher bioaccumulation than 6ppd-q?
- Notably, 6PPD-Q exhibited greater bioaccumulation than 6PPD, likely attributable to its slower clearance from the body, as evidenced by the higher urinary excretion of 6PPD compared to 6PPD-Q in mouse samples (Zhao et al., 2023c).
- What is the concentration of 6ppd-q in surface runoff?
- In surface runoff, the concentration of 6PPD-Q was found to be as high as 1,562 ng/L, significantly surpassing the concentration of the parent compound 6PPD, which had a maximum concentration of 7.52 ng/L. In addition, road runoff is an important carrier of TRWPs into water bodies.
