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.
ozonated 6ppd and twp samples, underscoring formation of diverse tps from this antioxidant. by screening environmental samples, nine 6ppd-derived tps were detected within roadway runoff. the data confirm that when tire rubber antioxidants react with ozone, as intended, they form and release various tps to surrounding environments.

occurrence of substituted p-phenylenediamine antioxidants in,the substituted p-phenylenediamines (ppds) represent a suite of effective antioxidants broadly applied in rubber industries. however, knowledge of their environmental occurrences and fate remains extremely limited. herein, we explored the occurrence of six major ppd antioxidants and one newly defined transformation product in dust particles from different environments, including roads.
6ppd rubber antioxidant: characteristics, applications
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.
screening p-phenylenediamine antioxidants, their,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.
- Are PPD antioxidants present in all samples dominated by 6PPD and dtpd?
- PPD antioxidants, PPDQs, and other TPs were present in all samples with chemical profiles dominated by 6PPD, DTPD, DPPD, and their corresponding PPDQs.
- Can abiotic processes reprogramme the toxicity of 6ppd-q?
- Additionally, it was observed that during UV treatment, hydroxyl groups were detected in the transformation products of 6PPD-Q (Wang et al., 2024), indicating that abiotic processes can induce hydroxylation, potentially reprogramming its toxicity.
- Does acetone remove 6PPD from waste rubber?
- A parity plot of the measured extraction efficiency versus the calculated 6PPD solubility (Fig. 2e) corroborates that solubility is a crucial determinant of the solvent’s ability to remove 6PPD from waste rubber and confirms that acetone is one of the best solvents while being inexpensive and non-toxic.
