Abstract

In this work, we synthesized (E)-2-hydroxyethyl 3-(4-oxo-4H-chromen-3-yl) acrylate (HCAE). 1H-NMR and 13C-NMR spectroscopy was used to characterize the compound. We examined the HCAE's anticorrosion characteristics at 100, 200, and 300 ppm concentrations in two distinct mediums, 3.5% NaCl and 1M HCl. Electrochemical spectroscopy (EIS) findings at 303K revealed that the HCAE inhibitor achieved 88.89% protection effectiveness in 1M HCl and 93.88% protection efficiency in 3.5% NaCl, demonstrating exceptional inhibition efficiency at 300 ppm. Furthermore, the efficacy of the HCAE in preventing corrosion was investigated through Scanning Electron Microscopy (SEM) to analyze the structural morphology of the protective layer that developed on the mild steel surface.
