Summary
Rate constants for the reactions of OH radicals with H2S, CH3SH, CH3SCH3 and. thiophene in the presence of various partial pressures of O2 at 700 Torr total pressure in N2 diluent have been measured in 38 1 and 420 1 reaction Chambers using competitive kinetic techniques. For CH3SH and CH3SCH3 the measured rate constants were found to increase with increasing pressure of O2. In the case of H2S and thiophene the rate constants showed no dependence on the pressure of O2 present in the system. The O2-dependence of the reaction of OH witn CH3SH and CH3SCH3 is discussed in terms of a mechanism involving the addition of OH to form a complex which can react with O2 or decompose back to the reactants. Possible reactions pathways for OH + H2S and thiophene are also discussed in terms of the present results and data available from the literature.
