摘要： 安替比林及其4位取代衍生物是较强的配位剂,可与不同的稀土盐作用生成组成各不相同的配合物,为了进一步探讨安替比林的衍生物对稀土离子的配位作用,我们研究了以4-一氯乙酰基安替比林(4-ClCH2COAP)为配体与硝酸镧或氧化镧的三元水盐体系。

Abstract: The solubilities and the refractive indexes of saturated solutions of the ternary systems 4ClCH2COAP-LaY3-H2O(Y=NO3-, Cl-) at 30℃ were studied and the corresponding equilibrium diagrams were constructed. The solubility curves and refractive index curves of nitrate systems consist of three branches, corresponding to 4-ClCH2COAP, La(4-ClCH2COAP)2(NO3)3 and La(NO3)3·6H2O. The ternary complex is incongruently soluble in water. The eutectic compositions are: La(NO3)3 49.80%, 4-ClCH2COAP0. 85% and La(NO3)3 60.63%, 4-ClCH2COAP 0.56%. The system of chloride is a simple one. The eutectic composition is LaCl3 48.39％, 4-ClCH2COAP 0.28%. The IRspectra and the X-ray powder diffraction of the ternary complex were studied too.
