应用温度跃迁装置和断流分光光度计分别研究了铜(Ⅱ)—2,9-二甲基邻菲啰啉与α-氨基酸和N-苯基乙二胺在25℃、0.1mol·dm~(-3)KNO_3水溶液中的生成反应动力学.实验结果表明在铜(Ⅱ)—2,9-二甲基邻菲啰啉—α-氨基酸三元配合物的生成速率常数与配体α-氨基酸的酸离解常数之间存在着如下的直线自由能关系:logk_f=2.84+0.53pK_2.根据 Eigen 机理讨论了铜(Ⅱ)—2,9-二甲基邻菲啰啉—N-苯基乙二胺三元配合物的生成反应动力学.
The effects of copper (Ⅱ) -2,9-dimethyl-phenanthroline, α-amino acids and N-phenylethylenediamine at 25 ℃, 0.1 mol · dm ~ (-3) KNO_3 aqueous solution.The experimental results show that the formation rate constant of copper (Ⅱ) -2,9-dimethyl-phenanthroline-α-amino acid ternary complex and the ligand α- Amino acid acid dissociation constants exist between the following linear free energy relationship: logk_f = 2.84 +0.53pK_2. According to Eigen mechanism of the copper (Ⅱ) -2,9- dimethyl phenanthroline-N-phenylethylene B Reaction kinetics of diamine ternary complex formation.
