Synthesis, characterization, Biological Activity, and corrosion inhibition study of two dyes from 4-aminophenol

Abstract

In the study, the reaction used to create the azo dyes (B and N)of 4-aminophenol with β-naphthol and 3-nitrophenol. These compounds were characterized by technology analysis as FT-IR and 1H-NMR and physical properties were assessed. The synthesis compounds of biological activity were studied against two types of bacterial positive-grams (Staphylococcus aureus) and negative-grams (E.coli) and given good results. The azo compounds were studied as corrosion inhibitors in the dissolution of carbon steel 45 in (0. 1M) HCl solution. the inhibitors of dyes were inspected using the polarization of technique. The compounds (B and N) show inhibition high efficiency.
