用旋转扩散池研究了肟配体Acorga P50萃取铜的动力学和机理。该反应被示出发生在水相和庚烷相之间的液/液界面上。提出了一个包括两个肟配体顺序加成的动力学方案，并测定了该方案的所有速率常数。这些数据不能用反应发生在水相中的模型来解释。在工业条件下的萃取和汽提反应的自由能分布的序列。
The kinetics and mechanism of the solvent extraction of copper, using the oxime ligand Acorga P50, have been studied with the rotating diffusion cell in both the extraction and striping directions. The reaction is shown to take place on the liquid/liquid interface between the aqueous and heptane phases. A kinetic scheme involving the sequential addition of two oxime ligands is proposed, and all the rate constants for the scheme have been measured. The data cannot be explained by models in which the reaction takes place in the aqueous phase. Sequences of free energy profiles for the extraction and stripping reactions under industrial conditions are presented.
