In the reactions of H atoms, generated by the Hg(3P1)-sensitized decomposition of H2, with C2H5SC2H5 the primary reaction has been established to be with k1 = (4.7 +/- 0.9) * 1013 exp cm3 mol-1 s-1 relative to the rate constant of the H + C2H4 --> C2H5 reaction.The mechanism postulated explains adequately all the experimental observations.The entropy of activation for the primary reaction, -22.1 eu is close to the value obtained for the H + CH3SCH3 reaction, suggesting a transition state with similar structure.H atoms do not abstract hydrogen from diethylsulfide, but the ethyl radicals from reaction on do with a rate coefficient of k = (7.4 +/- 0.5) * 1013 exp cm3 mol-1 s-1.
