transformation products of tire rubber antioxidant 6ppd in heterogeneous gas-phase ozonation: identification and environmental occurrence

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

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

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

Insight into the anti-aging mechanisms of natural phenolic antioxidants in natural rubber composites using a screening strategy

In the last decade, the rubber production capacity has increased significantly with an average annual increase rate of 16.1%. 1 However, rubber materials are prone to oxidation under the condition of heat, oxygen, and other parameters.

The discovery that the commercial rubber antidegradant 6PPD reacts with ozone (O3) to produce a highly toxic quinone (6PPDQ) spurred a significant research effort into nontoxic alternatives. This work has been hampered by lack of a detailed understanding of the mechanism of protection that 6PPD affords rubber compounds against ozone. Herein, we report high-level density functional theory

Balancing anti-migration and anti-aging behavior of binary antioxidants for high-performance 1,2-polybutadiene rubber - Wiley Online Library

However, the common low-molecular-weight antioxidants easily migrate to the rubber surface and lose the anti-aging effect. In this work, we develop highly anti-migration hindered phenolic antioxidants, which have been obtained by covalently grafting 3,5-di-tert-butyl-4-hydroxybenzoic acid (AO) onto carbon nanotubes (CNTs).
