| 摘 要： | 由于燃烧机理和大气化学过程研究的需要,人们对有机化合物分子,如烷烃、烯烃及其衍生物与一些自由基,如O、OH和卤素原子的反应速率常数进行了广泛的测定。但酮类分子与这些自由基的研究则报道得很少,尽管人们早已发现酮类化合物是碳氢化合物被NO_x光氧化过程中产生的中间化合物。就我们所知,除有少量的关于O(~3P))原子与酮类分子反应速率常数测定的文献报道外,我们在前文中报道了用流动微波放电——化学发光方法测

| Abstract: | The second order rate constants of the reaction between O(~3P) and 3-pentanone were measured over temperature range 313-513K with discharge flow-chemiluminescence technique. The dependence of the rate constant on temperature was determined to bek=1.41±0.46×10~(-10)exp(-5.76±0.07×10~3/1.987T)cm~8 molecule~(-1) s~(-1). |
