Rate constants for the reactions of OH radicals and Cl atoms with diethyl sulfide, Di‐n‐propyl sulfide, and Di‐n‐butyl sulfide

Abstract

Rate constants for the reactions of OH radicals and Cl atoms with diethyl sulfide (DES), di‐n‐propyl sulfide (DPS), and di‐n‐butyl sulfide (DBS) have been determined at 295 ± 3 K and a total pressure of 1 atm. Hydroxyl radical rate data was obtained using the absolute technique of pulse radiolysis combined with kinetic spectroscopy. The chlorine atom rate constants were measured using a conventional photolytic relative rate method. The rate constant for the reaction of Cl atoms with dimethyl sulfide (DMS) was also determined. The following rate constants were obtained:
