Study on the Solubilities of the System of Ln(ClO_4)_3-PCBAAP- _2O at 30℃

测定了两个三元系统Ln(ClO_4)_3-PCBAAP-H_2O(Ln=La,Yb;PCBAAP:4-(对氯苯酰基)氨基安替比林,C_(18)H_(16)N_3Cl)在30℃时的溶解度,发现两系统各有一个组成为Ln(PCBAAP)_4(ClO_4)_3·nH_2O(Ln=La,n=6;Ln=Yb,n=2)的不一致溶解化合物生成.参考系统的溶解度研究结果,合成了系列化合物Ln(PCBAAP)_4(ClO_4)_3·nH_2O(Ln=La,n=6;Ln=Pr,Nd,Sm,Gd,Yb,n=2),通过化学分析及元素分析,IR光谱,TG-DTG,XRD和密度测定对其进行了表征.

The solubilities of the ternary systems Ln(ClO4 )3 - PCBAAP - H2O (Ln = La, Yb) at 30℃ were determined, and the incongruent compounds, Ln ( PCBAAP )4 ( ClO4 )3·nH2O (Ln=La, n = 6; Ln = Yb, n = 2) were discovered in the systems . Based on the results of solubilities , the series compounds , Ln· (PCBAAP)4(ClO4)3· nH2O (Ln = La, n = 6; Ln = Pr, Nd, Sm, Gd, Yb, n = 2) were synthesized by means of phase equilibrium method. The compounds were characterized by chemical analysis, elemental analysis, IR spectra, TG - DTG analysis, XRD and density determination, respectively.
