研究了在３５±０．１℃，离子强度Ｉ＝０．１（ＫＣｌ）及有机酸（分别为乙酸、正丙酸、１．４－丁二酸）缓冲条件下，新型水溶性间－四（β－Ｎ－乙酸乙酯基吡啶基）卟啉（缩写为Ｈ２Ｔβ－Ｎ－ＥＡＥＳＰｙＰ４＋，以下简记为Ｈ２Ｐ４＋）与Ｃｕ（Ⅱ）的嵌入反应动力学。实验结果表明，在上述三种有机酸缓冲体系中，嵌入反应的速率方程具有相同的形式，反应速率对Ｃｕ（Ⅱ）和卟啉的浓度均为一级。发现三种有机酸均有明显催化作用。提出了反应机理，简单讨论了有机酸的催化作用。
A new type of water-soluble m-tetrazolium bromide was prepared under the conditions of 35 ± 0.1 ℃, ionic strength I = 0.1 (KCl) and organic acids (acetic acid, n-propionic acid, (Β-N-ethyl pyridyl) porphyrin (abbreviated as H2Tβ-N-EAESPyP4 +, hereinafter abbreviated as H2P4 +) and Cu (Ⅱ). The experimental results show that in the three organic acid buffer systems, the rate equation of the embedded reaction has the same form, and the reaction rate has the same order of the concentrations of Cu (Ⅱ) and porphyrin. Three kinds of organic acids were found to have obvious catalysis. The reaction mechanism was proposed and the catalytic action of organic acids was briefly discussed.
