| Abstract: | Polydentate neutral organophosphorus compounds attract great interest as efficient extractants of transplutonium elements(TPE) from acid waste nuclear fuel element solution. With the view of a further search, reagents R′R″-PO-CH2-CNO-R 2 ″' were synthetized and investigated. The solubility of R 2 ′ POCH2CNOR 2 ″' vas investigated in organic solvents and in nitric acid solutions. This reagent was found to be the best one. |
