| Abstract | ||
| A new azo dye derived from 2-Amino-6-ethoxy benzothiazol and 2-naphthol is prepared which decomposes at 179-180 C and identified by IR through the appearance of (N=N) group in the region 1520 cm-1 in addition to other bands that affirm the suggested structure of the compound.The UV –visible spectrum in dioxane solvent show two absorption bands ,the first at 378 nm is attributed to a( Л Л) transition with in benzothiazole group and the second at 490 nm is attributed to a ( Л Л) transition within the whole conjugated system in the molecule. The elemental analysis (CHN) affirms the rightness of the suggested structure of the compound by the accordance of both theoretical and practical results. | ||
