Popis:	N-(n-Alkyl)-N′-diphenylphosphorylureas Ph2P(O)NHC(O)NHCnH2n+1 (n = 6–10) were synthesized by the reaction of diphenylphosphoryl isocyanate with primary n-alkylamines CnH2n+1NH2. The products (especially N-diphenylphosphoryl-N′-n-octylurea) are efficient extractants capable of extracting actinides and lanthanides from nitric acid solutions with high distribution coefficients.
