摘要： 合成了PMBP苯甲酰基苯环上不同位置取代的3个衍生物2a、2b、2c,其中2b、2c为新化合物.制备了它们的酮体和烯醇体,并用元素分析和IR、UV、1HNMR进行表征和研究.与PMBP相对照,分别测定了2a、2b、2c的pKa值、对水相铀酰离子萃取的Kex、pH1/2和萃合物组成.在萃取条件下,它们对铀(Ⅵ)的萃取能力顺序是:2c>2b>2a>PMBP.

Abstract: In this paper, o,m,p- 4-(methoxy-benzoyl)-PMP (compounds 2a, 2b, 2c) have been synthesized by introducing methoxy to benzene ring of 4-benzoyl of PMBP.The keto and enol forms of these compounds have been prepared by the method of solvent crystallization and characterized by elemental analysis, IR, UVand 1H NMR.The keto-enol tautomerism of these compounds in different solvents and the influence of introducing methoxy to benzene ring of benzoyl of PMBPhave been studied.The pKa values of compounds (2a, 2b, 2c) have been determined.The extraction of U(Ⅵ) with these compounds(HA) have been studied in contrast to PMBPby slop method.The compositions of the complexes, the pH1/2, the logarithm of the extraction e-quilibrium constants lgKcx and the pKa.
