摘要: 合成了N 酰基吗啡啉(AMPHL)萃取剂,用红外,核磁共振,元素分析等方法对其结构进行了表征。研究了N 酰基吗啡啉的分子结构变化对萃取铀(Ⅵ)性能的影响。在实验酸度范围内,N 酰基吗啡啉萃取能力的增加顺序为:OMPHLAbstract: New extractants LMPHL, DMPHL, OMPHL are synthesized and their structures are identified by IR, 1H NMR and EA. The influence of molecule structure change on the capability of solvent extraction of U(Ⅵ) has been studied. The distribution ratio of U(Ⅵ) is different because of the different length of the carbon chain on the acyl moiety. The sequence of the extraction ability increases in the order of OMPHL
