在 25°C 和 0.1 M 离子强度 (Na2SO4) 下，对 8-羟基喹啉的 7-十二碳烯基取代衍生物 (Kelex 100) 及其铜 (II) 螯合物在氯仿和含有氨基多羧酸的水介质之间的分布平衡进行了研究，以检验分布常数与分子中碳原子数之间线性自由能关系假设的可能局限性。虽然 7-十二碳烯基-8-羟基喹啉的分布常数 KDR = 105.52 比使用相关参数从母体化合物预测的分布常数小三个数量级，但其铜 (II) 螯合物的分布常数 1010.03 与根据配体 KDR 计算的值非常一致。
A study of distribution equilibria of the 7-dodecenyl-substituted derivative of 8-quinolinol (Kelex 100) and its copper(II) chelate between chloroform and aqueous media containing aminopolycar☐ylic acids was carried out at 25° C and 0.1 M ionic strength (Na2SO4) to examine possible limitations of the hypothesis of linear free energy relationship between the distribution constant and the number of carbon atoms in the molecule. Although the distribution constant,KDR= 105.52, of the 7-dodecenyl-8-quinolinol was three orders of magnitude less than that predicted from that of the parent compound using correlation parameters, the distribution constant of its copper(II) chelate, 1010.03, was in good agreement with the value calculated on the basis of theKDRof the ligand.
