1.10—菲罗啉氮氧化物的合成性质及应用

Synthesis and Characterization of Phenanthroline Oxide and Its Ternary Coordination Compound of Rare Earth Elements

参照文献的方法并加以改进制备了1.10—菲罗啉氮氧化物(phenNO),合成了1—苯基—3—甲基—4—苯甲酰基—吡唑酮—5(HPMBP)和phenNO的三价轻稀土三元配合物[Nd(PMBP)_3·phenNO]。测定了phenNO的pk_a及用氯仿作溶剂时的两相分配常数logkd及该化合物和三元配合物的热谱、红外光谱,并对它们的组成进行了元素分析。研究了phenNO作为协萃剂用于HPMBP萃取稀土体系的协萃效应。

1,10—Phen enanthroline—1—oxide (phenNO) was synthesized according to the reference, but with some improvement: Its ternary coordination compound RE (PMBP)_3phenNO was synthe—sized through saturated extraction of RE with HPMBP and phenNO in chloroform solution. The pk_a and log Kd of phenNO were determined by potentiomeetric titration. RE(PMBP)_3 PhenNO and phenNO were characterized by IR spectra, elementary ana—lysis and thermographic curves. The synergic effect of phenNO to the extraction of RE with HPMBP was studied compara—tively with phen and its derivatives.
