Development of efficient extractants for the separation of actinides and lanthanides in the technologies of nuclear fuel cycle is one of the most urgent and complex tasks in modern nuclear energetics. New family of 4,7-dichloro-1,10-phenanthroline-2,9-dicarboxylic acid diamides based on cyclic amines was synthesized and shown to exhibit high selectivity in the La/Am pair separation (SF (Am/La ≈ 10)) and in
在核燃料循环技术中开发用于分离锕系和镧系元素的高效萃取剂是现代核能学中最紧迫和最复杂的任务之一。合成了基于环胺的新型 4,7-二氯-1,10-菲咯啉-2,9-二羧酸二酰胺,并显示在 La/Am 对分离中表现出高选择性 (SF (Am/La ≈ 10) ) 和 Am/Eu 对分离 (SF (Am/Eu ≈ 12))。结果表明,吡咯烷衍生的二酰胺比其非环状N , N , N ', N更有效地萃取强酸性 HNO 3溶液中的镅、锔和镧系元素。'-四烷基类似物。通过红外光谱、核磁共振光谱和单晶X射线衍射对合成化合物的结构进行了详细研究。根据光谱数据,芳环与配体的酰胺片段的结合导致溶液中复杂的动态行为,这被认为强烈影响合成配体的萃取能力。
