- Аннотация: The radiolysis of a radiochemical extraction system based on N,N,N',N'-tetra-n-octyl diglycolamide (TODGA) dissolved (0.15–0.2 M) in a mixture of Isopar-M with n-decanol or n-nonanol has been studied. The alcohol content was 6 or 20 vol %. A beam of 8-MeV electrons was used for irradiation. It has been found that the predominant radiolytic transformation of TODGA is fragmentation with the major formation of N,N-dioctylacetamide and 2-hydroxy-N,N-dioctylacetamide. Products of the dissociative addition of alkoxy radicals to the carbonyl groups of TODGA were detected. The total yield of TODGA degradation in the extraction system was no higher than 0.5 μmol/J. Degradation was insensitive to the type of alcohol, but it depended on the alcohol content of the solution.
