Synthesis of Some New Azo Disperse Dyes and Investigation of Their Solvatochromic Effect

Document Type : Research Paper




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