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.
