摘要: 利用GC/MS方法研究了SO2与1-己烯在无氧和有氧体系中光化学反应动力学.确定了SO2与1-己烯光化学反应的级数,给出了293-333K温度范围内总的反应速度常数K.以及K与温度的关系、反应的活化能和指前因子,另外,对反应产物已醛和2-己酮的生成巨应速度常数及其活化能也进行了计算和讨论.Abstract: The photochemical reaction kinetics of sulfur dioxide and 1-hexene in the absence or presence of oxygen system were studied using GC and GC/MS methods. The order and rate constants of photochemical reaction of sulfur dioxide and 1-hexene were given. According to Arrhenius equation,frequency factor and activation energies were obtained. In the paper,rate constants and activation energies of formating reaction of hexanal and 2-hexanone were calculated and discussed.
