Abstract

The kinetics of the reactions of F and C1 atoms with ethylene oxide have been studied using relative rate techniques in 10–700 Torr of either nitrogen or air diluent at 295 ± 2 K; k(F + C~2~H~4~O) = (9.4 ± 1.6) × 10^−11^ and k(C1 + C~2~H~4~O) = (5.0 ± 0.9) × 10^−12^ cm^3^ molecule^−1^ s^−1^. The result for k(F + C~2~H~4~O) is in good agreement with the literature data. The result for k(C1 + C~2~H~4~O) is a factor of 5.6 lower than that reported previously. It seems likely that in the previous study most of the loss of C~2~H~4~O attributed to reaction with C1 atoms was actually caused by unwanted secondary reactions leading to an overestimate of k(C1 + C~2~H~4~O). © 2001 John Wiley & Sons, Inc.
