| 摘 要： | 以降冰片二烯为原料，四乙基米氏酮为光敏剂，在无溶剂条件下，采用循环式反应器研究了降冰片二烯光敏异构反应动力学。结果表明，反应前期降冰片二烯的浓度下降较快，反应后期降冰片二烯的浓度下降变缓。反应速率可用一级反应动力学方程表达，反应活化能为29 173 J/mol，指前因子为1026 min-1。

| Abstract: | The kinetics of the photoisomerization of norbornadiene in the circulation reactor was investigated in the absence of solvent,with norbornadiene as raw materials and with 4,4 ’-bis（diethylamino） benzophenone as the triplet sensitizer.The results show that the concentration of norbornadiene drops quickly in the earlier stage,while it drops slowly in the later stage.The reaction rate can be expressed with a first-order reaction kinetics equation.The activation energy is 29 173 J /mol and the pre-exponential factor is 10.26 min-1. |
