1-苯基-3-甲基-4-苯甲酰基-吡啉酮-5(简称PMBP,本文用A表示)作为金属离子的螯合萃取剂早巳广泛应用,其与稀土离子形成的固态配合物也已报道了几十种,但Ce(Ⅳ)的加合物CeA_4·L(L=Dipy,Phen,Tbpo,Tppo)未见报道,我们合成了上述加合物,对它们作了IR、HNMR、UV和热谱等研究。 (一)实验部分 CeA_4L的合成:准确称取一定量的L,溶于苯中,加入计量的CeA_4(按文献[4]方 1-Phenyl-3-methyl-4-benzoyl-pyrazolone-5 (abbreviated as PMBP, referred to herein as A) has long been widely used as a chelate extractant for metal ions, However, Ce (Ⅳ) adducts CeA_4 · L (L = Dipy, Phen, Tbpo and Tppo) have not been reported yet. We synthesized the above adducts and made IR , HNMR, UV and heat spectrum and other research. (A) Experimental part of the synthesis of CeA_4L: Accurately weigh a certain amount of L, dissolved in benzene, adding metered CeA_4 (according to the literature [4]
