Abstract:
A new azo compound [2-((4-hydroxy-3-(E)-(2-hydroxy-5-nitrophenyl)diazenyl)benzaldeyde and the azo schiff derivative [2-((4-hydroxy-3-((E)-(2-hydroxy-5-nitrophenyl)diazenyl)benzylidene)amino)-4-nitrophenol (Azo-S) has been synthesized. 13C-NMR, 1H-NMR, FT-IR, Mass apectroscopy and Uv-Visibl analysis was used to characterized new compounds. The new synthesized compound Azo-S was utilized to inhibit mild steel (MS) corrosion at little concentrations (0.001-0.006) M. Weight loss measurements studies in 1 M HCl and at 298 K showed that Azo-S has a good corrosion inhibition efficiency, 75% at 0.002 M of inhibitors.It was found that adsorption methods follow Lanngmuir isotherm with ΔG values around -23.8 kJ/mol, this confirms that a stable protective film is formed for the mild steel spontaneously during physical adsorption.

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by...
