摘要：
The gas-pliase rate coefficient for the reaction between OH radicals and CH3SCH2Cl (MCDMS) was determined to be (2.5 +/- 1.3) x 10(-12) cm(3) molecule(-1) s(-1) using the discharge-flow kinetic technique. An estimate of approximate to 10(-10)cm(3) molecule(-1) s(-1) was obtained for the rate coefficient for reaction of Cl with MCDMS. It would appear that the reaction with OH is not the main loss process for CH3SCH2Cl in the marine boundary layer. The possible implications for the MBL of halogen-promoted oxidation of dimethylsulphide are considered. (c) 2006 Elsevier Ltd. All rights reserved.
