Abstract

Mild steel is a well-known and widely used material in various industries. However, its exposure to aggressive environments limits its use because of its tendency to corrode. This work focuses on the inhibition of corrosion of mild steel by two organic compounds based on Imidazole, namely 2-(4-chlorophenyl)-1,4,5-triphenyl-1H-imidazole and 1,2,4,5-tetraphenyl-1H-imidazole, in mixed pickling bath. The experimental investigation was carried out using several techniques including electrochemical impedance spectroscopy and potentiodynamic polarization. The adsorption process of corrosion inhibitors on the mild steel surface follows Langmuir adsorption model. Surface characterization analysis using scanning electron microscopy coupled with energy dispersive X-ray analysis (EDX), X-ray diffraction analysis (XRD) supported the formation of a barrier layer that covers the mild steel surface. Weight loss measurements were also tested using UV-vis spectrometry (UV-vis).

Abstract

In this chapter, the authors investigate recent advancements in the manufacture of chemical compounds containing a benzoxazepine-based heterocycle. Specifically, they synthesized the Benzoxazepine Derivatives using two organic reactions to test its efficacy as an inhibitor against the corrosion of mild steel in acidic pickling baths. The findings reveal that the corrosion inhibitor efficiency increased from 79.4% to 93.3%. This study also employed the Langmuir adsorption model to show that Benzoxazepine Derivatives studied adsorbed spontaneously on the metal surface with a mixed-type nature, forming a coating that is verified by SEM/EDS. The negative free energy of adsorption values and the significant relationship between the inhibitor molecule and the adsorption energy further support our findings. This study demonstrates the potential of benzoxazepine derivatives as effective inhibitors of mild steel corrosion in acidic pickling baths, with significant implications for the manufacturing industry. Continued research in this field is of utmost importance.
