First insights into 6PPD-quinone formation from 6PPD photodegradation in water environment

p-Phenylenediamines (PPDs), an important type of rubber antioxidants, have received little study on their environmental fate, particularly for their vital photodegradation process in water environment.Accordingly, N-(1,3-dimethylbutyl)-N¡ä-phenyl-1,4-phenylenediamine (6PPD), as a representative of PPDs, was investigated experimentally and theoretically for its photodegradation in water.

rubber antioxidants and their transformation products: environmental occurrence and potential impact

Rubber Antioxidants and Their Transformation Products: Environmental Occurrence and Potential Impact

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

New Evidence of Rubber-Derived Quinones in Water, Air, and Soil | Environmental Science & Technology - ACS Publications

Our results demonstrated that five rubber-derived quinones, including 6PPD-quinone, existed in the environment as the transformation products of PPD antioxidants. Such findings greatly expand the existing knowledge of PPD-derived quinones and thus may provide opening clues and promote further investigations on their environmental fate and ecological risks in the near future.

Rubber Antioxidants and Their Transformation Products: Environmental Occurrence and Potential Impact - PMC - National Center for Biotechnology

Antioxidants are added to natural rubber (NR) and synthetic rubber (SR) during mastication, which is the process of transforming rubber from a strong and elastic state to a soft and plastic state [ 4, 5 ]. In addition, they could also be coated on the NR surface to achieve a similar effect [ 6 ].

Transformation Products of Tire Rubber Antioxidant 6PPD in Heterogeneous Gas-Phase Ozonation: Identification and Environmental Occurrence - PubMed

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 ¡­

6ppd

6PPD

6PPD is a common rubber antiozonant, with major application in vehicle tires. It is mobile within the rubber and slowly migrates to the surface via blooming. Here it forms a "scavenger-protective film", reacting with the ozone more quickly than the ozone can react with the rubber. [4]
