Abstract

Using a relative rate technique the reactions of fluorine and chlorine atoms with CF~3~COOH have been determined to proceed with rate constants of (5.6 ± 0.7) × 10^−11^ and <1 × 10^−17^ cm^3^ molecule^−1^ s^−1^, respectively. Quoted errors for the F atom rate constant reflect statistical uncertainty (two standard deviations). Systematic errors could add an additional 20% uncertainty. Experiments were performed at 295 ± 2 K and 700 torr total pressure of nitrogen diluent. The reactions of Cl and F atoms with CF~3~COOH are of no atmospheric importance. Rainout is believed to be the dominant mechanism by which CF~3~COOH is removed from the atmosphere. The results from this study are discussed with respect to the design and interpretation of laboratory studies of the atmospheric chemistry of CFC replacements. © 1995 John Wiley & Sons, Inc.
