p-phenylenediamine antioxidants and their quinone derivatives,substituted p -phenylenediamines (ppds), a class of antioxidants, have been widely used to extend the lifespan of rubber products, such as tires and pipes. during use, ppds will generate their quinone derivatives (ppd-qs). in recent years, ppds and ppd-qs have been detected in the global environment.

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. [2]

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.

widely used good price rubber antioxidant ippd,in this study, we revealed the co-occurrence of six ppd-derived quinones (ppd-qs) along with eight ppds in fine particulate matter (pm 2.5) from two chinese megacities, in which n, n ′-bis (1,4-dimethylpentyl)- p -phenylenediamine quinone (77pd-q) was identified and quantified for the first time.

determination of phenolic content and antioxidant activity of

this work was aimed to evaluate the antioxidant activity and phenolic content in 40 commercial cosmetic creams available in syrian market. phenolic content was determined according to the folin–ciocalteu method using gallic acid as the standard. antioxidant activity of cosmetic creams were measured using the method of frap (ferric

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.

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...

n-isopropyl-n phenyl-p-phenylenediamine wiley online library,ozone and material fatigue are more important than its effects as an antioxidant. the main field of application for n-isopropylN'-phenyl-p-phenylenediamine is the tyre manufacturing sector.

widespread occurrence of two typical n, n’-substituted p

n, n’-substituted p-phenylenediamines (ppds) are typical synthetic antioxidants extensively utilized in the rubber industry, notably for their application in preserving rubber tires [1], [2].

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.
