rubber antioxidants and chemical 6ppd,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 .
6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
Best Price Rubber Antioxidant 6PPD CAS No.: 793-24-8
we demonstrate the catalytic upgrade of 6ppd to safe chemicals and the valorization of crumb rubber to aromatics and carbon black using microwave-assisted pyrolysis.
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.
6ppd rubber antioxidant: characteristics, applications
6ppd (n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a highly effective rubber antioxidant with notable characteristics, including excellent heat resistance, anti-flex cracking properties, and compatibility with various rubber types.
first grade quality 6ppd rubber antioxidant,recently, roadway releases of N-(1,3-dimethyl-buty)-N'-phenyl-P-Phenylenediamine (ppd) antioxidants and their transformation products (tps) received significant attention due to the highly toxic 6ppd-quinone. however, the occurrence of ppds and tps in recycled tire rubber products remains uncharacterized.
environmental occurrence and toxicity of 6ppd quinone, an
(6ppd) is a chemical added to tires to protect them from oxidative degradation. with good dispensability in sizing material and little effect on vulcanization, It can soften sizing material, so can be used for tires and other kinds of rubber products.
environmental fate of tire-rubber related pollutants 6ppd,To improve tire durability, the antioxidant n-(1,3-dimethylbutyl)-n-phenyl-p-phenylenediamine (6PPD) is used in rubber, but when exposed to oxidants such as ozone (O3), it is converted into toxic 6PPD quinone (6PPD-Q), causing ecological problems.
chemical characteristics, leaching, and stability of the
We report here the fate and transport-related chemical characterization of the recently discovered environmental toxicant 6ppd-quinone (2-((4-methylpentan-2-yl)amino)-5-(phenylamino)cyclohexa-2,5-diene-1,4-dione or "6ppd"). 6ppd is a transformation product of the tire rubber antioxidant 6ppd.
rubber antioxidant 6PPD price antioxidant 4020,to address this data gap, we first analyzed crumb rubbers from artificial turf fields and recycled rubber doormats for ppd antioxidants, ppdqs, and five other ozonation or aqueous reaction tps of 6ppd6,25,39 (figure 1) using liquid chromatog-raphy-tandem mass spectrometry (lc-ms/ms).
