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.
N(1,3-dimethyl-butyl)-N'-phenyl-P-phenylenediamine chemical active antioxidant
infobox references. n-isopropyl-n′-phenyl-1,4-phenylenediamine (often abbreviated ippd) is an organic compound commonly used as an antiozonant in rubbers. [1] like other p-phenylenediamine -based antiozonants it works by virtue of its low ionization energy, which allows it to react with ozone faster than ozone will react with rubber. [2]

p‑phenylenediamine antioxidants in pm2.5: new markers for traffic in,in the traffic source factor profiles, the load of ippd, cppd, dppd, dnpd and 6ppd reaches 91.8 %, 91.6 %, 92.9 %, 80.6 % and 87.2 %, respectively. it`s amazing that traditional markers of traffic source, which often overlap with coal burning and industrial sources, over-estimated the contribution of vehicles by one third or more.

new evidence of rubber-derived quinones in water, air, and soil,five p-phenylenediamine-derived quinones have been identified to be pervasive in roadside soil, runoff water, and air particles, while their health risks remain elusive. research findings demonstrate the coexistence of five quinones from globally ubiquitous p-phenylenediamine antioxidants in urban runoff, roadside soils, and air particles. 1.
- Are PPD antioxidants toxic?
- An increasing number of studies have focused on the toxicity of these PPD antioxidants. (8−10,15,33) According to the European Chemical Agency, several of them were labeled as very toxic to aquatic life with long-lasting effects and harmful if swallowed and may cause an allergic skin reaction.
- Can antioxidant protection be used to detect PPDS and TPS?
- An efficient and stable method for the detection of PPDs and their TPs was developed. Oxidative degradation is the main cause of low extraction efficiency of PPDs and some TPs. Combined strong antioxidant protection for stable extraction PPDs and their TPs was first proposed.
- Is 6PPD a good metabolite?
- Metabolism of PPDs in the human body remains unclear (Zhu et al., 2024). Studies on mice showed that after oral gavage, 6PPD concentrations in mice urine were > 10 times higher than its quinone metabolite (6PPDQ) (Zhao et al., 2023b), indicating the low biotransformation efficiency of 6PPD.
- Is IPPD a toxicity hazard?
- IPPD may have heightened toxicity compared to other common anti-degradants and accelerators, as has been demonstrated previously with Daphnia magna ( Wik, 2007 ). As a result, the continual detection of IPPD is of particular concern, and its inhalation exposure and toxicity should be evaluated along with the other PPDs.
