| 摘 要： | 以变色酸为母体设计合成了对羧基偶氮羧碘显色剂，磺酸基是该显色剂的功能团，从对氨基苯甲酸出发，进行磺化，得2—氨基—5—羧基苯磺酸．将它重氮化。与变色酸二钠盐偶联．得偶氮羧磺I，再以偶氮羧磺I为母体．与对氨基苯酸偶联，得对羧基偶氮羧磺。

| Abstract: | In this thesis,a new reagent p-carboxylic carboxysulfonazo has been designed and synthesized.Sulfonazo is azo reagents of chromotropic acid containing functional group-SO 3H.First,carboxysulfonazol was synthesized from p-amino-benzoic acid by sulfonation and diazothzation and azo coupling with chromotropic acid respectively.Then,the new bisazo reagent was synthesized from carboxysulfonazol by azo coupling with corresponding diazonium salt of substituted aniline. |
