Abstract
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.
