The Synthesis of New Reagent P-Carboxylic Carboxysulfonazo

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.
