摘要
合成了均苯四甲酸锰、邻苯二甲酸锰。利用热重、元素分析和红外光谱仪对产物进行了表征。热重和元素分析的结果确定了这2种配合物的分子式分别为Mn2(C10H2O8).6H2O和Mn(C8H4O4)。将它们与醋酸锰进行比较,通过热重分析,得出了3种无水配合物的热稳定性次序:Mn(C8H4O4)>Mn2(C10H2O8)>Mn(C2H3O2)2。红外分析的结果表明,所得产物除具有与醋酸锰相同官能团的特征峰之外,还具有苯环的特征峰,且可以判断其取代位置分别为1,2,4,5取代和1,2取代。
Manganese complexes with pyromellitic acid and o-phthalic acid were synthesized. They were characterized by TG, element analysis and FTIR. TG and element analysis results show that their formula are Mn2 （C10H2O8）·6H2O and Mn（C8H4O4）, respectively. Compar with manganese acetate, the thermal stability of three anhydrous manganese complexes is obtained by TG analysis, and the sequence is Mn（C8H4O4） 〉Mn2（C10H2O8） 〉Mn（C2H3O2）2. IR analysis indicates that manganese complexes with pyromellitic acid and o-phthalic acid possessed the phenylic characteristic peaks in addition to functional groups like manganese acetate. 1,2,4,5- tetra-substitutions of Mn2 （C10H2O8）·6H2O and ortho-substitutions of Mn（C8H4O4） are identified by IR analysis.
