the effect of antioxidant concentration of n-isopropyl-n,the purpose of this study is to compare the effect of anti-oxidants types ippd and tmq and mixing time of vulcanization of the physical properties, mechanical properties, microstructure and elemental composition of the synthesis of natural rubber compound.
N-Isopropyl-N'-phenyl-p-phenylenediamine (often abbreviated ippd) is an organic compound commonly used as an antiozonant in rubbers. 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.

rubber antioxidants and chemical 6ppd
amine antioxidants are the main rubber antioxidants produced and used in china, of which 6ppd and 2,2,4-trimethyl-1,2-dihydroquinoline (tmq, rd) have the highest production, accounting for more than 80% of the total amine antioxidants.
6ppd rubber antioxidant: characteristics, applications,6ppd (n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a highly effective rubber antioxidant with notable characteristics, including excellent heat resistance, anti-flex cracking properties, and compatibility with various rubber types.
transformation products of tire rubber antioxidant 6ppd for sale
6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), 6PPD is compatible with a wide range of rubber types, including natural rubber and various synthetic rubbers, making it versatile for different formulations.
rubber antioxidants: tmq, 6ppd, ippd chemical products,tmq, also known as polymerized 2,2,4-trimethyl-1,2-dihydroquinoline, is a widely used rubber antioxidant. it provides excellent protection against heat, oxygen, and flex-cracking, enhancing the durability and performance of rubber products.
influence of different types of antioxidants on the aging
ippd and 6ppd are antioxidants and antiozonants of p-phenylenediamine type and they are widely used in various recipes for technical goods. antioxidants of ppd type can result in high temperature stability, high strength, and chemical and electrical resistance [ 31 ].

on the dehydrogenation of n,n′-substituted p-phenylenediamine
using b3lyp/6-31g ∗ treatment, the optimal geometries, electronic structures and ir spectra of n -phenyl- n ′-isopropyl- p -phenylenediamine antioxidant (ippd) and its doubly dehydrogenated oxidation products have been obtained.
widespread occurrence of two typical n, n’-substituted p,in the healthy cohort, 6ppd (0.13 ng/ml) had the highest median concentration, followed by 6ppd (0.057 ng/ml) and ippd (0.050 ng/ml). similarly, for the s-nafld cohort, 6ppd (0.20 ng/ml) had the highest median serum concentration, followed by 6ppd (0.071 ng/ml) and ippd (0.040 ng/ml).
- Do substituted para phenylenediamine (PPD) antioxidants affect the environment?
- Substituted para -phenylenediamine (PPD) antioxidants have been extensively used to retard oxidative degradation of tire rubber and were found to pervade multiple environmental compartments. However, there is a paucity of research on the environmental occurrences of their transformation products.
- Are 6PPD and IPPD a contaminant?
- 6PPD and IPPD were detected in white shrimp samples collected from aquafarms. Given the high toxicity of N- (1,3-dimethylbutyl)-N’-phenyl- p -phenylenediamine (6PPD) derivatives, such as 6PPD quinone (6PPDQ) to salmon, as well as their ubiquitous presence in the environment, the contaminant of aquatic food products has drawn significant attention.
- What is the most effective anti-oxidant?
- Specifically, L-AP, L-AA, 3,5-DTBA, and DTT increased the recovery to over 60%, with L-AA demonstrating the most significant effect. L-AA is widely recognized as a low-cost and potent antioxidant that captures free radicals such as 1 O 2 , . Consequently, L-AA was selected as the protective agent.
- Which compound has the highest antioxidant levels in Guangzhou & Taiyuan?
- The same trend was also observed in its parent compound, 6PPD, which showed the highest proportion among these antioxidants in Guangzhou (46%), with a median level of 1820 pg/m 3, while that in Taiyuan was only 20%, with a median value of 81.0 pg/m 3 ( Table 1 ).
