The invention relates to novel extracting agents and novel propane diamides, their use for the recovery of actinides and/or lanthanides and their preparation process. These extracting agents are constituted by propane diamides of formula: ##STR1## For example, the extracting agent can be 2-hexyl-N,N'-dimethyl-N,N'-dibutyl-propane diamide or 2-ethoxyethyl-N,N'-dimethyl-N,N'-dibutyl-propane diamide. They are more particularly used for the recovery of actinides and/or lanthanides present in the trivalent state in an acid aqueous solution, particularly in a nitric solution.
该发明涉及新型萃取剂和新型丙烷二酰胺,它们用于回收锕系元素和/或镧系元素以及它们的制备过程。这些萃取剂由式子为:##STR1## 的丙烷二酰胺组成。例如,萃取剂可以是2-己基-N,N'-二甲基-N,N'-二丁基丙烷二酰胺或2-乙氧基乙基-N,N'-二甲基-N,N'-二丁基丙烷二酰胺。它们特别用于回收三价锕系元素和/或镧系元素,这些元素存在于酸性水溶液中,特别是硝酸溶液中。
