The Kinetic Study of Reactions of O（³p） with Alcohol Molecules

The measurement results of the rate constants of reactions between O（³p） atoms and alcohol molecules with discharge flow-chemiluminescence technique are presented. Over temperature range of 293—503K. the rate constants of O（³p） atoms with propanol,2—propanol, butanol, tert- butanol, tert-amyl alcohol and iso-amyl alcohol are (3.22_-1.08^+1.67×10¹¹exp(-（3.6±0.3）kcal·mol^-1/RT), (5.59_-1.32^+1.73×10^-12 exp(-（2.4± 0.2） kcal·mol^-1/RT), (5.4l_-1.07^+1.33)× 10^-11exp(-（3.1 ± 0.2） kcal·mol^-1/RT), (4.95_-0.81^+0.96)× 10^-10exp(-（6.00 ± 0.14） kcal ·mol^-1/RT), (1.08_-0.13^+0.15)×10^-9 exp(-（6.01 ± 0.10） kcal·mol^-1/RT) and (6.29_-1.04^+1.24)× 10^-11exp(-（2.51± 0.14） kcal·mol^-1/ RT), respectively (Units are cm³·molec^-1. s^-1). The estimation of the Arrhenius parameters of the reactions between O（³p） and the abstracted hydrogen atoms in different positions of alcohol molecules is also presented.
