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.
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.
hot sale rubber antioxidant 6ppd for tyre/shoes
to examine the effects of o 3 on 6ppd transformation and tp formation in tire rubber matrices, twps were exposed (6 h) to o 3 (360 ± 12 ppbv) or zero-grade air in triplicate glass columns (1 ×.
end-of-life tire decontamination from 6ppd and upcycling nature,abstract. n (1,3-dimethylbutyl)- n ′-phenyl- p-phenylenediamine (6ppd) is a ubiquitous rubber antioxidant and antiozonant that extends the lifetime of common rubber products, such as those.

ples.28−32 6ppd is ubiquitously used in tire rubbers as an antioxidant at 0.4−2% by weight,33 where it is designed to quickly react with ground-level o 3 to protect rubber elastomers.34,35 such reactions inevitably form other trans-formation products (tps) beyond 6ppdq during the tire rubber lifetime.21,34 for example, early studies on the
chronic exposure to tire rubber-derived contaminant 6ppd,the half-life of 6ppd-q is significantly longer than that of 6ppd [7]; consequently, the distribution of 6ppd-q has been widely reported in various environmental settings, including the atmosphere, aquatic systems, terrestrial soils, and sedimentary deposits influenced by wind and rainfall [8].

leveraging high-resolution mass spectrometry, we identified 19 probable 6ppd-derived tps in both ozonated 6ppd and twp samples, underscoring formation of diverse tps from this antioxidant. by screening environmental samples, nine 6ppd-derived tps were detected within roadway runoff. the data confirm that when tire rubber antioxidants react
environmental fate of tire-rubber related pollutants 6ppd and,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, and.

sunlight-induced transformation of tire rubber antioxidant n,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.
