Abstract

The rate constants for reactions of OH with ClCH~2~CH~2~Cl, Cl~2~CHCHCl~2~, BrCH~2~CH~2~Br, CH~3~CH~2~Br 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^ cm^3^ molecule^−1^ s^−1^, and E~a~'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.

The reactions of S + OH -SO + H (1) and SO + OH -SO2 + H (2) were studied in a discharge flow reactor coupled to an EPR spectrometer. The rate constants obtained under the pseudo-first-order conditions with an excess of S or SO were found to be k l = (6.6 f 1.4) X lo-" and k p = (8.4 f 1.5) X lo-" a
