| Popis: | The cis-syn-cis isomer of the dicyclohexano-18-crown-6 ether (DCH18C6) was subjected to hydrolysis and radiolysis with a 137Cs gamma source, at different doses of irradiation. The cis-syn-cis DCH18C6 radiolytic products previously identified [1], were synthesized in their different configurations. These radiolytic products, all of cis configuration, were tested on aqueous synthetic solutions of spent nuclear fuels. Experiments in radioactive medium showed that, under continuous extraction conditions, the cis-syn-cis DCH18C6 radiolytic products cannot perturb a reprocessing process using the DCH18C6 as selective extractant. Good prospects for the application of DCH18C6 to spent nuclear fuel reprocessing were therefore demonstrated. An X-ray crystallographic study of the DCH18C6 cis-syn-cis-isomer with uranyl nitrate was investigated. |
