摘要
以没食子酸（３，４，５－三羟基苯甲酸）为原料，合成了６种新型偶氮化合物．所有化合物经元素分析，部分化合物经ＩＲ及ＭＳ裂解碎片分析确定其结构，井研究这些化合物作为Ｔｉ（Ⅳ）、Ｇｅ（Ⅳ）、Ｉｎ（Ⅲ）、Ｇａ（Ⅲ）等离子显色剂的显色性能．
Six gallic acid azo compoundds were synthesized from gallic acid (3, 4 ,5-trihydroxy benzoicacid). Their stractrures were determined by element analysis, IR and MS. Furthermore, colorationexeperiments were also conducted to observe their analytical performances. It shows that these azo dyescan be used as chromogenic agents for Ti ( Ⅳ ) , Ge ( Ⅳ ) ,In ( Ⅲ) , Ga (Ⅲ ) etc .
