ملخص المقالة :

The synthesis and properties of new monoazo dyes derived from the diazonium salts of paminobenzoic acid, 3-trifluoromethyl aniline , 4-trifluoromethyl aniline are considered .Theprepared compounds were characterized by UV-Visible , FT-IR and H NMR spectroscopictechniques . The effect of varying solvent upon the absorption ability of p-amino benzoic acidcoupled with 4,4 —diethyl aniline , aniline ethanol, 2 — naphthol and 2,4 -dihydroxy benzene wasexamined.
