O（^3P）原子与丙醛和正丁醛化学反应动力学研究

The Kinetic Study of Reactions of O(~3p) with Propionaldehyde and Butyraldehyde

<正> 我们已对O(~3p)原子和酮类分子化学反应速率常数进行了系列测定,分析讨论了羰基对O(~3p)抽提氢原子反应速率的影响,关于O(~3p)与醛类分子反应速率的测定也有报道。本文用流动微波放电-化学发光光子计数方法测定O(~3p)原子与丙醛和正丁醛化学反应速率常数及其与温度的关系,并由动力学数据对醛基中C—H键的离解能进行了讨论。

The determinations of the rate constants of reactions of O(3p) atoms with propionaldehydeand butyraldehyde by discharge flow-chemiluminescence are presented. The results measured are asfellows: (for propionaldehyde+O(3p))and (for butyraldehyde + O(3p))The dissociation energies of C-H bond of aldehydic group are derived from the kinetic results.
