Synthesis and Characterization of Novel Corrosion Inhibitor Derived from Oleic Acid: 2-Amino 5-Oleyl-1,3,4-Thiadiazol (AOT)

Novel corrosion inhibitor as a green chemical product namely derivative, 2-amino 5-oleyl-1,3,4-thiadiazol (AOT) was synthesized by cyclization of oleic acid. The new corrosion inhibitor was characterized by FT-IR and NMR spectroscopical methods. AOT was evaluated as corrosion inhibitor for mild steel in 1M of Hydrochloric acid solution using Potentiodynamic and Electrochemistry Impedance Spectroscopy (EIS) technique. Results obtained show that AOT acts as a good corrosion inhibitor for mild steel in HCl solution. Theoretical studies were also done for the novel compound AOT.
