Abstract
2-Amino-N′-((thiophen-2-yl)methylene)benzohydrazide (ATMBH) was synthesized by a conventional method, as well as by microwave (MW) irradiation. The MW assisted synthesis of ATMBH was found to have good yield and was more eco-friendly compared to the conventional method of synthesis. The synthesized compound ATMBH was characterized by FTIR, 1H NMR, 13C NMR and CHN analysis. The corrosion inhibition performance of ATMBH in 0.5 M H2SO4 was analyzed by gravimetric and electrochemical methods. The potentiodynamic polarization study revealed that ATMBH acted as a mixed type of inhibitor. The results obtained from these methods are in good agreement and are well supported by the contact angle measurements.
