The rate constants for the ozone reactions with n-butyl methyl sulfide (n-BMS, CH3CH2CH2CH2SCH3), sec-butyl methyl sulfide (s-BMS, CH3CH2(CH3)CHSCH3) and tert-butyl methyl sulfide (t-BMS, (CH3)3CSCH3) were measured using our smog chamber under supposedly pseudo-first-order conditions at 300±2 K and 760 Torr. The experimental determined rate constants for n-butyl, s-butyl and t-butyl methyl sulfide are (1.23 ± 0.06)×10-19, (5.08 ± 0.19)×10?20 and (2.26 ± 0.14)×10?20 cm3·molecule-1·s-1, respectively. The reactivity-structure relationship of the reactions was discussed and used to illustrate the mechanism of the ozone reaction with thioethers. The results enrich the kinetics data of atmospheric chemistry.
The rate constants for the ozone reactions with n-butyl methyl sulfide (n-BMS, CH3CH2CH2CH2SCH3), sec-butyl methyl sulfide (s-BMS, CH3CH2 (CH3) CHSCH3) ) 3CSCH3) were measured using our smog chamber under supposed first-order conditions at 300 ± 2 K and 760 Torr. The experimental determined rate constants for n-butyl, s-butyl and t-butyl methyl sulfide are (1.23 ± 0.06 ) × 10-19, (5.08 ± 0.19) × 10-20 and (2.26 ± 0.14) × 10-20 cm3 · molecule-1 · s-1, respectively. The reactivity-structure relationship of the reactions was discussed and used to illustrate the mechanism of the ozone reaction with thioethers.
