| Abstract | ||
| This study involves the preparation of three azodyes derived from 1-hydroxy- 2-naphthoic acid and sulfadiazine derivatives. The characterization of Dyes 4-(sulfadiazineazo)-1-hydroxy-2-naphthoic acid ( F1) ,4-(sulfamerazineazo)-1-hydroxy2-naphthoic acid (F2) and 4-(sulfamethazineazo)-1-hydroxy2-naphthoic acid ( F3) have been described by C.H.N. The I.R. and V. & UV. spectroscopic techniques were carried out . The acid-base properties were studied at different pH values and the dissociation and protonation constants of dyes were determined, as well as the solvents effect were studied at different solvents polarities | ||
