Abstract
New six azo dyes derived of 5-pyrazolone were synthesized. La the four position of-5-pyrazolone were introduced the diasonium salts of the f ollowing compounds: -4-ethoxy-4-amino-methylbenzoate; phenylanilide of 4-amino-benzoic acid; 2-hidroxy-aniline; a-napthylamine; 1-amino-2-hi droxy-4-sulfonic acid. The new azo dyes synthesized were investigated by elemental analysis, melting paints, IR, UV-VIS, NMR methods and X-r ay determinations.
