芳香羟肟类化合物作为铜(Ⅱ)的特效萃取剂,已广泛地应用于湿法冶金工业。研究铜(Ⅱ)-芳香羟肟类配合物的结构与其萃取性能之间的关系,对于合理选择或设计配体的结构,可以提供有用的依据。 由于铜(Ⅱ)离子的顺磁性,ESR波谱能为这类配合物的结构提供重要的信息。我们曾报道过这类配合物在室温下的ESR波谱。近年来,O’Brien报道了某些商品羟肟类萃取剂如:SME-529,P-50以及Lix-63等的铜(Ⅱ)配合物的ESR波谱。 为了进一步研究这类芳香羟肟萃取剂对铜(Ⅱ)的萃取能力,我们合成了上述芳香羟肟类
As a special copper (Ⅱ) extractant, aromatic hydroxyoxime compounds have been widely used in the hydrometallurgy industry. Studying the relationship between the structure of copper (II) -aromatic hydroxyoxime complexes and their extraction performance can provide a useful basis for the rational selection or design of ligand structure. Due to the paramagnetic properties of copper (II) ions, ESR spectroscopy can provide important information for the structure of these complexes. We have reported the ESR spectra of these complexes at room temperature. In recent years, O’Brien reports the ESR spectra of copper (II) complexes of certain commercial hydroxyoxime-type extractants such as SME-529, P-50 and Lix-63. In order to further study the extraction ability of this kind of aromatic hydroxyoxime extractant to copper (Ⅱ), we synthesized the above aromatic hydroxyoximes
