Relative rate coefficients (in cm3 molecule−1 s−1) 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:k(OH+DES)=(1.65±0.71)×10-11,k(Cl+DES)=(3.14±0.89)×10-10,k(OH+EMS)=(1.11±0.29)×10-11,k(Cl+EMS)=(3.06±0.42)×10-10.
OH自由基和Cl原子与二乙基硫化物(DES)和乙基甲基硫化物(EMS)气相反应的相对速率系数(以cm 3分子-1 s -1为单位)已在298 K和大气压下长时间测定。原位FTIR分析路径:k(OH + DES)=(1.65±0.71)×10-11,k(Cl + DES)=(3.14±0.89)×10-10,k(OH + EMS)=(1.11± 0.29)×10-11,k(Cl + EMS)=(3.06±0.42)×10-10。
