| 摘 要： | 本文合成了硼合甘油希土和硼合葡萄糖希土二类共八个配合物。用化学分析、红外光谱、紫外光谱及热谱确定其组成为:RE(BO_2·C_3H_8O_3)_3·nCH_3OH和RE(BO_2·C_6H_(12)O_6)_3·3H_2O(RE=Nd、Gd、Y、Yb)。摩尔电导测定表明这两类化合物均为中性配合物。红外光谱显示出硼与多羟基醇之间以硼氧四面体形式结合。本文还通过电位滴定法讨论了希土与硼合多羟基醇之间的配位作用。

| Abstract: | In this work, eight compounds of rare earth with glycerin-boric acid and glucose-boric acid have been synthesized. The composition of these coordination compounds was determined by chemical analysis, IR spectra, UV spectra and thcrmogravimctric analysis. Results show that the composition of these coordination compounds is corresponding to the formula of RE(BO2 ?C3H8O3)3 ?nCH3OH and RE(BO2 ?C6H12O6)3 3H2O (RE = Nd, Gd, Yb,Y). As determined via molar conductance these compounds are characterized as neutral complexes. Based on the IR spectra data, boratc ion is combinated with polyols in form of BO4. In this paper, we researched the coordination action of rare earth ion with polyhydroxy-boric acid by potcntiomctric titration also . |
