This work includes preparation of Az, Qz, and Tz derivatives from the reaction
of Schiff base (Sb) derivative with anthranilic acid, chloroacetyl chloride, and
sodium azide, as well as, the characterization via FT-IR, 1H-NMR, and 13CNMR. The anticorrosion inhibition of these compounds was studied and the
measurements of carbon steel (CS) corrosion in sodium chloride solution
3.5% (blank) and inhibitor in solutions were calculated at a temperature
range of 293-323 K by the technique of electrochemical polarization. In
addition, some thermodynamic and kinetic activation parameters for inhibitor
and blank solutions (Ea⋇, ΔH⋇, ΔS⋇, and ΔG⋇) were determined. The results
showed high inhibition efficacy for all the prepared compounds,
