摘要
利用国产 Na^(15)NO_3试剂合成关键中间体^(15)N-盐酸羟胺,并研制成五种^(15)N-芳香羟肟及其过渡金属 Cu(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ)、Fe(Ⅱ)配合物,均达分析纯。
It is well-known that the ortho-aromatichydroxyoximes are excellent extractants forextraction of copper(Ⅱ)in the hydrometallurgy.Their specific extraction performances are clo-sely related to the structure of the complex.In the present paper the isotope labellingtechniques for elucidating these structures ofcomplexes by spectral analyses such as IR,MS,ESR and NMR has been reported.^(15)N-Salicyl-aldoxime,2-hydroxy-acetophenone oxime,2-hydroxy-benzophenone oxtime,2-hydroxy-4-me-thoxy-benzophenone oxime,2-hydroxy-5-me-thyl-henzophenone oxime,as well as their Cu(Ⅱ),Ni(Ⅱ),Co(Ⅱ),Fe(Ⅱ)complexes wereprepared for this purpose.Since ^(15)N-hydoxyl-amine is an importantintermediate for the syn-thesis of ^(15)N-hydroxyoxime,in this report twomethods of preparing this key compound bychemical reduction of Na^(15)NO_2 and electrochemical reduction of H^(15)NO_5 have been des-cribed briefly.
