“FTIR relative rate constants of the reactions of ethyl and methyl sulfide with OH radicals and Cl atoms”

Article

Summary *

Relative rate coefficients (in cm3 molecule1 s1) for the gas-phase reactions of OH radicals and Cl atoms with diethyl sulfide (DES) and ethyl methyl sulfide (EMS) have been determined at 298 K and atmospheric pressure using long path in situ FTIR analysis: with diethyl sulfide (DES) and ethyl methyl sulfide (EMS) have been determined at 298 K and atmospheric pressure using long path in situ FTIR analysis: 3 molecule1 s1) for the gas-phase reactions of OH radicals and Cl atoms with diethyl sulfide (DES) and ethyl methyl sulfide (EMS) have been determined at 298 K and atmospheric pressure using long path in situ FTIR analysis:in situ FTIR analysis: kðOH þ DESÞ ¼ ð1:65  0:71Þ  1011;ðOH þ DESÞ ¼ ð1:65  0:71Þ  1011; kðCl þ DESÞ ¼ ð3:14  0:89Þ  1010;ðCl þ DESÞ ¼ ð3:14  0:89Þ  1010; kðOH þ EMSÞ ¼ ð1:11  0:29Þ  1011;ðOH þ EMSÞ ¼ ð1:11  0:29Þ  1011; kðCl þ EMSÞ ¼ ð3:06  0:42Þ  1010:ðCl þ EMSÞ ¼ ð3:06  0:42Þ  1010: The rate coefficients did not show any dependence on the oxygen partial pressure and are compared with previous determinations. Reactivity trends and atmospheric implications are discussed. Information provided by the agent in SIGEVA
