Abstract
A dissymmetric RN,N-dialkylamides of formula (I) in which: Rrepresents a linear Cto Calkyl, Rrepresents a linear Cto Calkyl, and Rrepresents a linear or branched Cto Calkyl, where Ris different from a n-octyl, n-decyl, n-dodecyl, 2-ethylhexyl and 2-ethyloctyl group when Rrepresents a n-butyl group and Rrepresents an ethyl group. A method for synthesising the N,N-dialkylamides, and uses of same for extracting uranium and/or plutonium from an aqueous acid solution or for fully or partially separating the uranium from the plutonium contained in an aqueous acid solution and a solution resulting from the dissolution of spent nuclear fuel in nitric acid. A method for treating an aqueous solution resulting from the dissolution of spent nuclear fuel in nitric acid, which allows the uranium and the plutonium contained in the solution to be extracted, separated and decontaminated in a single cycle.
