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.
transformation products of tire rubber antioxidant 6ppd for sale
6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
widely used good price rubber antioxidant ippd,n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd) is the most widely used antioxidant in automobile tyres and many rubber products. we investigated the impact of 6ppd and 6ppd quinone on acute toxicity, morphol., swimming behavior, heart rate, and oxygen consumption in zebrafish larvae.
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 anti-aging agent antioxidant 6PPD (4020) supplier,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.

- 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.
- What causes 6ppd-q in soil and tire rubber wear particles (TRWPS)?
- There is a linkage between 6PPD-Q in soil and tire rubber wear particles (TRWPs), indicating its origin from sources associated with vehicular activities (Klockner et al., 2019). Approximately 50% of TRWPs can infiltrate the soil, releasing bound chemicals like 6PPD (Klockner et al., 2019).
- 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.
- Which GC GC is used to identify 6PPD and fatty acid products?
- An Agilent 8890 GC connected to a 5977B GC MSD with a DB-5 column was used to identify and quantify 6PPD and fatty acid products. The COSMO-RS method was used to perform solid–liquid solubility calculations. The Amsterdam Modeling Suite COSMO-RS was used.
