The complex was confirmed by spectra methods. The dynamics of complexation reaction was studied. The reaction rate law was determined to be first-order with respect to H2OEPSB and half-order forcobalt （Ⅱ） salt at 65～80℃ and the apparent activation energy was found to be 88.16 kJ.mol-1. The possible complexation reaction mechanism was proposed. 八乙基卟啉 西佛碱 钴（Ⅱ）卟啉 配位反应动力学 octaethylporphyrin Shiff-base cobalt（Ⅱ） porphyrin coordination reaction dynamics O614.812 高等学校博士学科点专项科研基金(20120141110002) 1996-02-01 2021-04-01 2
