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.
washington d.c.—the push to find an alternative to the tire antidegradant 6ppd—an additive that is critical to consumer safety but can transform into an offshoot chemical that is fatal to some fish species—continues for the u.s. tire manufacturers association.

6ppd chemical active antioxidant
6ppd is a common rubber antiozonant found in vehicle tires. it is mobile within the rubber and slowly migrates to the surface via blooming. on the surface it forms a "scavenger-protective film" that reacts with the ozone more quickly than the ozone can react with the rubber. this process forms aminoxyl radicals and was first thought.

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.
buy 6ppd antioxidant; price, uses, and analysis
6ppd antioxidant is one of the chemicals used in the rubber industry. to buy this product at the best price, please contact our experts in shanghai chemex. cas number: 793-24-8 made in: china packing: 25 kg bags,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.
rubber antioxidants and their transformation products,the oxygen consumption rate was increased rapidly in 15 min in rtgill-w1 cell after being exposed to 5–80 μg/l 6ppd-quinone, implying the tissue-specific toxicity of 6ppd-quinone . 6ppd-quinone was also observed to be highly toxic to silver salmon with an lc 50 of 0.79 ± 0.16 μg/l, which is almost three orders of magnitude lower than that.
- What is 6PPD used for?
- 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. [ 1 ] Although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance. It is one of several antiozonants based around p -phenylenediamine.
- Are PPD antioxidants present in all samples dominated by 6PPD and dtpd?
- PPD antioxidants, PPDQs, and other TPs were present in all samples with chemical profiles dominated by 6PPD, DTPD, DPPD, and their corresponding PPDQs.
- Is 6PPD recalcitrant under harsh pyrolysis?
- This demonstrates the recalcitrant nature of 6PPD under harsh pyrolysis conditions and suggests solvent extraction is necessary for its removal. The TGA curve (Supplementary Fig. 11) of 6PPD shows a maximum degradation at ~300 °C and suggests that some 6PPD in the tires may sublime into the liquid product before the rubber degrades.
- Does 6PPD survive microwave-assisted pyrolysis?
- With legislation on the horizon to ban 6PPD entirely, developing effective methods for its removal and conversion to safe compounds is essential. Here we show that 6PPD survives microwave-assisted pyrolysis and escapes in the oil product, rendering decontamination essential.
