- Аннотация: The reaction rate constant of a chlorine atom with dimethyl sulfide (DMS) is measured in the temperaturerange 308–366 K by the method of resonant fluorescence (RF) of chlorine atoms. It is shown thatthe reaction rate constant decreases during experiments at a higher temperature. At a temperature of 308 K,the rate constant of this reaction is measured at different ratios of the reaction time and the diffusion time ofchlorine atoms to the reactor wall. The data of these experiments show that with an increase in the diffusiontime of the active centers to the surface of the reactor, compared with the contact time of the reagents, adecrease in the measured reaction rate constant is observed. This allows us to assert that the reaction is heterogeneousand the interaction of the chlorine atom with the DMS occurs on the surface of the reactor.
