Abstract: Three new chelating agents of phenylenediacyl bis 1-phenyl-3-methylpyrazol-5-one (PMP) end groups have been synthesized. Their structures have been characterized by elemental analysis,UV,IR,1H NMR and MS spectra. The extraction of U(Ⅵ) with these compounds have been studied.The values of the pH1/2, logKex and chemical composition of the complexes have been obtained by the slope analysis method.

Key words: phenylmethylpyrazolone, phenylenediacyl compound, chelating agent, synthesis, extraction, U( Ⅵ)
