novel antioxidants based on polymerized 2,2,4-trimethyl-1,2,new derivatives of tmq antioxidant; ester, hydrazide, oxadiazole and triazole are synthesized and characterized through ftir and 1 hnmr. the formed polymers are examined for their antioxidant efficiency in sbr compounds.
transformation products of tire rubber antioxidant 6ppd for sale
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: tmq, 6ppd, ippd chemical products,Rubber antioxidant 6ppd, n-1,3-dimethylbutyl-n'-phenyl-p-phenylenediamine, is a synthetic rubber antioxidant widely used in the tire and rubber industry. It prevents degradation caused by heat, oxygen and flex cracking. 6ppd acts as a stabilizer and antiozonant, preventing the formation of harmful free radicals and extending service life
- Can TMQ be used as a tire antioxidant?
- This study aimed to design eco-friendly derivatives of 2,2,4-trimethyl-1,2-dihydroquinoline (TMQ) with increased antioxidant activity to use as tire antioxidants. Initially, seventy highly efficient derivatives of TMQ were designed by hydroxylation modifications at multiple sites.
- 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.
- Why are TMQ derivatives used as ligands important?
- TMQ derivatives used as ligands can be used as an indicator of the developmental toxicity risk for the corresponding designed hydroxyl derivatives of TMQ. The low values of binding energy indicate the high stability of docking complexes and hence high toxicity.
- Are tire antioxidants toxic to aquatic organisms?
- Various antioxidant derivatives are produced during the process of free radical scavenging by tire antioxidants. The toxic effects of some of these derivatives on aquatic organisms are reviewed in the literature. Tian et al. found that 6PPD-quinone, a derivative of tire antioxidant 6PPD, can cause acute death of silver salmon (Tian et al. 2021 ).
