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
Due to the need for combustion mechanisms and atmospheric chemistry studies, a wide range of reaction rate constants have been determined for molecules of organic compounds such as alkanes, alkenes and their derivatives with free radicals such as O, OH and halogen atoms. However, few studies have been reported on ketones and these free radicals, although ketones have long been found to be intermediates in the photooxidation of hydrocarbons by NO x. To the best of our knowledge, except for the few reports on the determination of the reaction rate constants of O (~ 3P) atoms and ketones, we reported in the previous report that the mobile microwave discharge-chemiluminescence
