a nation-wide study for the occurrence of ppd antioxidants,introduction. N-(1,3-dimethyl-buty)-N'-phenyl-P-Phenylenediamines (ppds) are extensively used antioxidants in rubber products especially tires (noordermeer et al., 2004). it is reported that the annual production of tires was nearly 3.1 billion pieces worldwide (tian et al., 2021).
diphenylamine based antioxidants. the product (alone or in combination with iirco tmq) provides compound protection against catalytic degradation by copper and other heavy metals.
New design rubber antioxidant IPPD CAS No 101-72-4
antioxidants such as n-phenyl-n‘-al-kylbenzene-1,4-diamines (ppd), with aromatic secondary amine groups are of the most common and important types of antidegradants in the tire industry [5,6]; since their main role is to reduce the rate of oxidation [3].
rubber antioxidants and their transformation products,rubber products are mainly used in industrial and agricultural production, transportation, and national defense construction, and antioxidants are a group of the most important chemicals with widespread use in rubber products.
rubber antioxidants and chemical 6ppd
antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life.
widely used chemical rubber antioxidant ippd,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.

improvements of lanthanum complex on the thermal-oxidative
mixed antioxidants composed of antioxidant ippd and novel rare earth lanthanum complex were used as an additive to prepare natural rubber (nr) samples. the variations of macro-properties, surface characterizations, and internal groups were investigated by mechanical testing, x-ray photoelectron spectroscopy, and thermogravimetric analysis
accurate and stable detection of p-phenylenediamine,in this study, we developed a stable, rapid, and sensitive analytical method combining salt-out-assisted extraction, antioxidant protection, and m-pfc clean-up to determine ppds and their tps (6ppd, ippd, 6ppd, ippdq, 4-adpa, 4-hdpa, and 4-ndpa) in aquatic products.

rubber antioxidant 6PPD price antioxidant 4020, N(1,3-dimethyl-butyl)-N'-phenyl-p-phenylenediamine (ppds) are widely used as antioxidants in the rubber industry.1,2 various ppds, including 6ppd (n-(1,3-dimethylbutyl)-n′-phenyl-p-phenyl-enediamine), ippd (n-isopropyl-n′-phenyl-1,4-phenylenedi-amine), 7ppd (n-(1,4-dimethylpentyl)-n′-phenyl-p-phenyl-enediamine), 77pd (n,n′-bis(1,4-dimethylpentyl)-p-phenyl-ene...
- 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.
- Do p-phenylenediamine antioxidants oxidize during pretreatment?
- There are relatively few reports on the content of p-Phenylenediamine antioxidants (PPDs) and their transformed products (TPs) in aquatic products. Quantifying PPDs, PPDQs, and other TPs is challenging owing to their tendency to oxidize and decompose during pretreatment, especially in organisms.
- 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.
- Why are 6PPD and IPPD only detected in shrimp?
- Only 6PPD and IPPD were detected in shrimp. Section 3.2 shows that 6PPD, IPPD, 4-HDPA, and 4-ADPA were degraded more readily in fish and crab than in shrimp, which may explain why 6PPD and IPPD were only detected in shrimp.
