transformation products of tire rubber antioxidant 6ppd for sale,abstract: 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.

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.

accurate and stable detection of p-phenylenediamine,in this study, we developed a stable, rapid, and sensitive analytical method combining salt-out-assisted extraction, antioxidant protection, and m-pfc clean-up to determine ppds and their tps (6ppd, ippd, 6ppd, ippdq, 4-adpa, 4-hdpa, and 4-ndpa) in aquatic products.

to the best of our knowledge, this is the first systematic investigation of the occurrence of major ppd antioxidants and 6ppd-qunione in various dust matrices. our findings would attract attention to their environmental fate and ecological and human health risks.

untargeted metabolomic analysis reveals a time-course hepatic,additionally, 6ppd exposure induced oxidative stress in zebrafish larvae, resulting in cardiotoxicity (fang et al., 2023a). the effects of 6ppd on mammals have also been documented in relevant literature. fang et al. (2023b) reported that 6ppd induced the upregulation of genes involved in pyruvate synthesis, lipid synthesis, and transport.

tire-derived contaminants 6ppd and 6ppd-q: analysis, sample

one such chemical is 6ppd-quinone (6ppd-q), a transformation product of the tire antioxidant 6ppd. in urban stormwater runoff 6ppd-q can exceed acute toxicity thresholds for several salmonid species and is being implicated in significant coho salmon losses in the pacific northwest.

first grade quality 6ppd rubber antioxidant,here, we analyzed tire wear particles (twps), recycled rubber doormats, and turf-field crumb rubbers for seven ppd antioxidants, five ppd-quinones (ppdqs), and five other 6ppd tps using liquid chromatography-tandem mass spectrometry.

the pollution level of ppds in pm 2.5 exhibited significant variability across years. notably, 6ppd, a dominant species of ppds, demonstrated a substantial increase, with concentrations from 2017 to 2020 being 1.30, 3.72, 7.10, and 8.85 times higher than those in 2016 (fig. 2 c, table s5).

evidence for the formation of 6ppd-quinone from antioxidant,fig. 5 shows the following available route to 2,4 im c4-oh for dissociation of the 6ppd quinol from the heme pocket, whose conversion into a resting-state of cyp450 and a free 6ppd quinol was exothermic (∆ ̅ g ≠ dis = -10.3 kcal/mol). however, there should be a driving force for the tautomerization of the 6ppd quinol into its much more
