transformation products of tire rubber antioxidant 6ppd for sale
abstract: 6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.
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.
transformation product formation upon heterogeneous ozonation
here, we investigated tp formation occurring during heterogeneous reaction of gas-phase ozone with the common tire rubber antioxidant 6ppd (n-(1,3-dimethylbutyl)N'-phenyl-p-phenylenediamine); exposures included both pure compound and twp rubbers. oxidative transformation occurred during ozonation (∼360 ppbv), with up to 81% of 6ppd mass
Best Price Rubber Antioxidant 6PPD CAS No.: 793-24-8,n-(1,3-dimethylbutyl)N'-phenyl-p-phenylenediamine (6ppd) is a ubiquitous rubber antioxidant and antiozonant that extends the lifetime of common rubber products, such as those...
Rubber Antiageing Antiage Antioxidant 4020/6PPD price
this study revealed that sunlight-induced transformation of 6ppd could be an important origin of 6ppd-q in aquatic environments, providing significant insights to the potentially underestimated ecological risks of 6ppd.
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.
technical data sheet (tds) with high quality
it is the efficient antioxidant used in tire industry and widely used for rubber products. it can completely avoid the tire surface to become red due to the use of antioxidant 6ppd and ippd. application: it is can be used for load tires, cross-country tires and various tires and bias-ply tires.
rubber antioxidants and their transformation products,the tps of rubber antioxidants have been observed in some studies under environmental conditions. as one of the widespread rubber antioxidants, amine antioxidants (ppds: tmppd, dppd, 6ppd, and 6ppdtz) could react with o 3 (in parts per billion volume levels) in the environment and produce ppd-quinone [31].
