transformation products of tire rubber antioxidant 6ppd price
abstract: 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 thestructures,reactionmechanisms,andenvironmentaloccurrenceof tps from 6ppd ozonation.
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.

- 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.
- 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 pyrolysis?
- The liquid pyrolysis oil product distribution and solid carbon black powder from the 1.3 mm and 0.6 mm particles are independent of the starting particle size (Fig. 1d); however, gas chromatography–mass spectrometry (GC–MS) of the oil product shows that 6PPD survives appreciably after pyrolysis (Supplementary Fig. 10).
- 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.
