eco-friendliness rubber antioxidant tmq for tire,initially, seventy highly eficient derivatives of tmq were designed by hydroxylation modifications at multiple sites. the antioxidant activity of hydroxyl derivatives was characterized based on dft method and compared with tmq.
due to the strong antioxidant activity of hydrazide, 1,3,4-oxadiazoles and 1,2,4-triazoles, our goal is to study the chemical modification of tmq (commercial antioxidant for rubber) by insertion of hydrazide, 1,3,4-oxadiazole and 1,2,4-triazole moieties to its backbone.
synthesis of 2,2,4-trimethyl-1,2- h -dihydroquinoline (tmq
tmq (2,2,4-trimethyl-1,2-h-dihydroquinoline) is an important antioxidant because of relatively low price and ease of application in rubber production technologies. however, due to the limited experimental data and unclear reaction mechanism, the quality of the tmq product needs to be improved in industry processes.
Factory Hot Sale Rubber antioxidant In Stock,Antioxidant for natural rubber and various synthetic rubbers, especially suitable for preventing thermal degradation of nitrile rubber. This product can be used in heating containers and tropical areas.
rubber antioxidants and their transformation products
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.
recent progress in the rubber antioxidants Rubber Auxiliary Agent,the antioxidative effect of silica-s-tp for rubber composite is superior to for the traditional antioxidants such as 4020, rd, 2246 and 264, and the high efficiency free radical capturing activity of silica-s-tp was stem from the polyphenol on the silica surface.
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.
synthesis of 2,2,4-trimethyl-1,2-dihydroquinolines over metal,besides pharmacological applications, tmq is additionally considered as a very important and effective industrial antioxidant in rubber technologies and also employed in preserving animal nutriments and vegetable oils [5, 6, 7, 8, 9].
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.
safe protection against oxidation lanxess,lanxess markets the antioxidant tmq (2,2,4-trimethyl-1,2-dihydroquinoline) under the trade name vulkanox hs for the production of tires and heavy-duty technical rubber goods.
- Is TMQ a good antioxidant?
- TMQ (2,2,4-trimethyl-1,2-H-dihydroquinoline) is an important antioxidant because of relatively low price and ease of application in rubber production technologies. However, due to the limited experimental data and unclear reaction mechanism, the quality of the TMQ product needs to be improved in industry processes.
- Is TMQ a solvent-process model?
- An improved dynamic process model is formulated. A case study for solvent-process design of TMQ production is highlighted. TMQ (2,2,4-trimethyl-1,2-H-dihydroquinoline) is an important antioxidant because of relatively low price and ease of application in rubber production technologies.
- Which hydroxyl derivatives of TMQ have the lowest toxicity risk?
- TMQ-6 and TMQ-48 are the hydroxyl derivatives of TMQ, with the lowest toxicity risk and the highest antioxidant activity among all the hydroxyl derivatives considered in the study. These results provide guidelines and support for future efforts toward designing highly efficient and eco-friendly tire antioxidants.
- Which TMQ molecule has the highest antioxidant activity?
- TMQ-6 and TMQ-48 have higher antioxidant activity than TMQ molecules by 9.05% and 11.79%, respectively. TMQ-6 and TMQ-48 are the hydroxyl derivatives of TMQ, with the lowest toxicity risk and the highest antioxidant activity among all the hydroxyl derivatives considered in the study.
