6ppd rubber antioxidant: characteristics, applications, combinations
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.
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.
sunlight-induced transformation of tire rubber antioxidant n-(1,3
the huge consumption of the tire rubber antioxidant n-(1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) has resulted in pervasive contamination in aquatic environments. more importantly, the transformation product of 6ppd, i.e., 6ppd-quinone (6ppd-q), is raising increasing concerns due to its high toxicity to aquatic organisms. however, whether and how 6ppd-q can be formed from 6ppd in.
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.
chemical characteristics, leaching, and stability of the ubiquitous
we here report chemical characteristics relevant to the fate and transport of the recently discovered environmental toxicant 6ppd-quinone (2-((4-methylpentan-2-yl)amino)-5-(phenylamino)cyclohexa-2,5-diene-1,4-dione or “6ppdq”). 6ppdq is a transformation product of the tire rubber antioxidant 6ppd that is ubi
environmental fate of tire-rubber related pollutants 6ppd and 6ppd-q: a,abstract. to enhance tire durability, the antioxidant n- (1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) is used in rubber, but it converts into the toxic 6ppd quinone (6ppd-q) when exposed to oxidants like ozone (o 3), causing ecological concerns. this review synthesizes the existing data to assess the transformation, bioavailability.

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 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.
- 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 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.
- How does microbial Fe (III) reduction affect the formation of 6ppd-q?
- In the initial aging stage, microbial Fe (III) reduction transforms 6-PPD into 6PPD-Q (Xu et al., 2023b). Subsequently, the formation of 6PPD-Q is facilitated by environmentally persistent free radicals (EPFRs), resulting in the generation of O 2 •-, indicating the potential formation of 6PPD-Q without ozone presence (Xu et al., 2023b).
