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.
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.
rubber antioxidants: tmq, 6ppd, ippd chemical products
6ppd, or n-1,3-dimethylbutyl-n’-phenyl-p-phenylenediamine, is a synthetic rubber antioxidant widely used in the tire and rubber industry. it provides protection against degradation caused by heat, oxygen, and flex-cracking. 6ppd acts as a stabilizer and antiozonant, preventing the formation of harmful free radicals and extending the service life of rubber products.
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.

a ubiquitous tire rubber–derived chemical induces acute science,we tested this hypothesis with gas-phase ozonation (500 ppbv o 3) of industrial grade 6ppd (96% purity) (). a c 18 h 22 n 2 o 2 product formed; uplc-hrms analysis demonstrated exact matches of retention time (11.0 min) and ms/ms spectra between this synthetic c 18 h 22 n 2 o 2 and the twp leachate fractionation-derived c 18 h 22 n 2 o 2 ( fig. 2, a and b ).
cheap price chemicals rubber antioxidant 6ppd
to examine the effects of o 3 on 6ppd transformation and tp formation in tire rubber matrices, twps were exposed (6 h) to o 3 (360 ± 12 ppbv) or zero-grade air in triplicate glass columns (1 ×.
rubber antioxidants and their transformation products mdpi,antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber.
- Which industrial rubber additives have higher chemical concentrations?
- Furthermore, we quantified 15 other industrial rubber additives (including bonding agents, vulcanization accelerators, benzotriazole and benzothiazole derivatives, and diphenylamine antioxidants), observing that PPD-derived chemical concentrations were 0.5–6 times higher than these often-studied additives.
- Is 6PPD a dangerous hazard?
- Various aquatic species have shown severe susceptibility to 6PPD-Q 3, 4. 6PPD has been detected in humans 5 and causes severe developmental, physical deformative and behavioral health effects 6. Crumb rubber derived from EOL tires is used in asphalt and recreational fields, with 6PPD shown to leach from these spaces 7.
- How does 6PPD affect the environment?
- 6PPD and 6PPD-Q tend to accumulate in aquatic environments, persisting and intensifying their harmful effects on aquatic organisms and ecosystems over time. During production and usage, 6PPD is released and combined with particulate matter to form 6PPD-Q in the atmosphere by reacting with ozone.
- Does 6PPD survive pyrolysis?
- The liquid pyrolysis oil product distribution and solid carbon black powder from the 1.3 mm and 0.6 mm particles are independent of the starting particle size (Fig. 1d); however, gas chromatography–mass spectrometry (GC–MS) of the oil product shows that 6PPD survives appreciably after pyrolysis (Supplementary Fig. 10).
