利用IR、1 H -NMR和1 3 C -NMR研究了不同结构酰胺与UO2 +2 形成萃合物的结构 ,发现胺基对萃取剂的配位能力有较大的贡献。萃取剂羰基红外吸收峰和羰基碳化学位移的变化规律与磺化煤油中双取代酰胺萃取铀结构 -性能规律相一致。
The IR, 1 H-NMR and 1 3 C-NMR spectra of different structures of amide and UO2 +2 were used to characterize the structure of the complex. It was found that the amine group has a great contribution to the coordination ability of the extractant. The changes of carbonyl IR absorption peak and carbonyl carbon shift of the extractant are in accordance with the structure-property law of uranium extracted by bis-substituted amides in sulfonated kerosene.
