recent progress in the rubber antioxidants price,in this review, we summarized the recent advances in rubber antioxidants over the last 10 years and offered some perspectives to outline the challenges and future research directions for the rubber antioxidants. 2. brief introduction of the oxidation process and oxidation mechanism of the rubbers.
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]
understanding antioxidant agent 4010na (ippd),antioxidant agent 4010na, scientifically known as ippd (n-isopropyl-n'-phenyl-p-phenylenediamine), is a prominent antioxidant widely employed in various industrial and consumer applications. its role in preventing oxidative degradation and enhancing the longevity and performance of materials is unparalleled.

environmental chemical rubber antioxidants,according to the different fracture modes of the molecular chain of raw rubber materials, different chemical antioxidants are added to block the growth reaction chain during aging []. chemical antioxidants are generally classified as amine, phenolic, heterocyclic, phosphite, and nickel salts (nickel dibutyl dithiocarbamate (nbc)) antioxidants according to their chemical structure ( figure 1 ).
- Which PPD is most commonly used?
- Among the various PPDs, N- (1,3-dimethylbutyl)-N’-phenyl- p -phenylenediamine (6PPD) and N-isopropyl-N’-phenyl-1,4-phenylenediamine (IPPD) are high-production-volume chemicals and the most frequently used . In 2020, China produced 200,000 tons of 6PPD, representing nearly 54% of the total production of rubber antioxidants .
- How many PPDS are produced in China in 2020?
- In 2020, China produced 200,000 tons of 6PPD, representing nearly 54% of the total production of rubber antioxidants . PPDs are highly reactive towards oxygen and ozone, resulting in various transformation products (TPs) that pose a risk to the environment and organisms .
- What are the commercial products of heterocyclic antioxidants?
- The commercial products of heterocyclic antioxidants mainly include 2-mercaptobenzimidazole (MB), 2-mercaptomethylbenzimidazole (MMB), 2-mercaptobenzimidazole zinc salt (MBZ), 2-mercaptomethylbenzimidazole zinc salt (MMBZ) and the benzothiazole derivatives . Among them, MB and MBZ are the two most common products.
- Are PPDS ubiquitous in China?
- Eight PPDs (6PPD, 7PPD, DPPD, IPPD, 77PD, CPPD, DTPD, DNPD) and six PPD-quinones (IPPD-quinone, CPPD-quinone, 6PPD-quinone, 77PD-quinone, DPPD-quinone, DTPD-quinone) were also detectable in PM 2.5 collected from three sites located in Taiyuan and Guangzhou, China . This indicated that atmospheric PPDs and PPD-quinones are ubiquitous in China.
