end-of-life tire decontamination from 6ppd and upcycling nature,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 found in tires. it.
transformation products of tire rubber antioxidant 6ppd price
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,rubber antioxidants are defined as substances that could delay the aging of polymer compounds and prolong the service life of rubber products by inhibiting oxidation, heat, or light radiation . to date, the annual global consumption of rubber antioxidants is over 700,000 tons, accounting for about 40% of the total amount of rubber additives.
- 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.
- Does 6PPD ozonation pose environmental risks?
- 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.
- Does acetone remove 6PPD from waste rubber?
- A parity plot of the measured extraction efficiency versus the calculated 6PPD solubility (Fig. 2e) corroborates that solubility is a crucial determinant of the solvent’s ability to remove 6PPD from waste rubber and confirms that acetone is one of the best solvents while being inexpensive and non-toxic.
- What solvent is used to remove 6PPD from EOL tires?
- Through batch extraction analysis and computational calculations, acetone is the best suited solvent for 6PPD removal from EOL tires of those tested. Furthermore, the batch extraction kinetics follow a first-order profile.
