摘要：

We have measured rate constants for the reactions of the hydroxyl radical, OH, with a number of fluorinated ethers. These ethers and their calculated atmospheric lifetimes for removal by OH (in years), estimated relative to CH3CCl3, are as follows: CF3-O-CH3, 3.0; CF3-O-CHF2, 19; CHF2-O-CHF2, 2.6; CF3CH2-O-CH3, 0.1; CF3CH2-O-CHF2, 5.2; cyclo-CF2CHFCF2-0, 26; cyclo-(CF2)3-O, >330.
