Temperature dependent kinetics of the reaction OH + CF3CH2CF3

We have re-examined the kinetics of the reaction of OH with CF3CH2CF3 (FC 236fa) between 281 and 337 K using highly purified reactant. After accounting for the contribution to the measured rate of all measured impurities, we derive a room temperature rate constant k = (4.15 ± 0.33) × 10−16 cm3 s−1, a factor of two smaller than our earlier report [J. Geophys. Res. 98 (1993) 23, 107] and in general agreement with other recent measurements.
