摘要 在30℃时采用等温溶度法研究了三元体系Sm(NO_3)_3-ACAP-H_2O(ACAP,4-acetylan-tipyrine,4-乙酰基安替比林)的相平衡,绘制了体系的溶度图及饱和溶液的折光率一组成图.发现并制备了未见文献报道的同成分溶解的化合物Sm(ACAP)_2(NO_3)_3.通过化学分析、元素分析、摩尔电导(DMF),IR和TG-DTG对其进行了物理化学性质表征.初步探讨了阴离子对ACAP与稀土相互作用的影响. The solubilities and the refractive indexes of saturated solutions of the titled system at 30℃ have been studied and the correspounding equilibrium diagram and refractive index diagram were constructed. Both solubility curve and refractive index curve of the system consist of three branches, correspounding to ACAP, Sm(ACAP)2(NO3)3 and Sm(NO3)3 · 6H2O respectively. The Sm(ACAP)2(NO3)3 is a new compound. It was characterized by chemical and elemental analysis, IR spectra, TG-DTG and molar conductivity (in DMF). The influences of the anion on the interaction between the ACAP and the rare earth ion has been discussed briefly.
