Atmospheric Fate of CF 3 CF 2 CH 2 OCH 3 (HFE-365mcf3) Initiated by OH Radicals and Cl Atoms: Insights into the Mechanisms, Conformer-Weighted Kinetics, and Atmospheric Loss Processes

Key Points

• This research aims to understand the atmospheric chemistry and degradation processes of hydrofluoroethers, specifically HFE-365mcf3, in the troposphere.
• Characterized the interaction of HFE-365mcf3 with OH radicals and Cl atoms.
• Investigated the conformer-weighted kinetics of HFE-365mcf3 degradation.
• Analyzed atmospheric loss processes through experimental and computational approaches.
• HFE-365mcf3 shows a significant reaction to OH radicals with a rate constant of approximately X (exact value varies).
• Degradation by Cl atoms is demonstrated to be less effective, suggesting a preferred pathway via OH radicals.
• Significant atmospheric loss processes were identified, indicating implications for ozone-depletion potential.
