| 摘 要： | 为了研究模拟过氧化物酶催化降解苯酚的机理,一种大环金属配合物CuL(配体L:高氯酸-5,7,7,12,14,14-六甲基-1,4,8,11-四氮杂环-4,11-二烯)作为模拟过氧化物酶用于催化过氧化氢氧化苯酚的降解。用高效液相色谱法和分光光度法分析了苯酚催化氧化的主要产物和反应速率。根据实验结果提出了该催化反应的反应机理,并建立了相关的动力学模型。研究表明,大环铜金属配合物表现出过氧化物酶的催化作用特征。因此,所用大环铜配合物作为模拟过氧化物酶在催化苯酚氧化过程中是一种有效的催化剂。

| Abstract: | To study the mechanism of phenolic oxidation catalyzed by the mimetic peroxidase,a macrocyclic metal complex CuL(L: 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraaza-cycloteradeca-4,11-diene per-chloride) was used as mimetic peroxidase in the catalytic oxidation of phenol by H2O2.The main products and reactive rate of phenol catalytic oxidation were detected with HPLC(high-pressure liquid chromatography) and the spectrometer;the mechanism of the catalytic reaction was proposed and the relational kinetic model was founded.It shows that the macrocyclic copper complex exhibits the catalytic characteristics of peroxidase.The macrocyclic copper complex as mimetic peroxidase is an effective catalyst in the catalytic oxidation of phenol. |
