Kinetics studies of reactions of OH radicals with four haloethanes part I. Experiment and BEBO calculation

The rate constants for reactions of OH with ClCH2CH2Cl, Cl2CHCHCl2, BrCH2CH2Br, CH3CH2Br have been measured by using a discharge flow‐resonance fluorescence (DF‐RF) technique over the temperature range 293–418 K. The rate constants as a function of temperature were fitted to the Arrhenius expression as follows: (k's units are 10−12 cm3 molecule−1 s−1, and Ea's units are cal/mol) The experimental data have been compared with theoretical calculations of the semi‐empirical BEBO‐transition state method. Life‐times of the four haloethanes in the troposphere have been estimated.
