Abstract

A green corrosion inhibitor 2-(α-hydroxyethyl)benzimidazole was synthesized via the reaction between ortho phenylene diamine and DL-lactic acid in aqueous solution. The as-synthesized compound was crystallized using methanol and characterized by melting point analysis, proton nuclear magnetic resonance (PMR) and Fourier transform infrared (FTIR) spectroscopy. A weight loss method was used to evaluate the corrosion inhibition property of 2-(α-hydroxyethyl)benzimidazole on mild steel corrosion in 1.0 M HCl solution. The corrosion inhibition study reveals that, the synthesized and recrystallized product acts as good corrosion inhibitor.

Keywords: green corrosion magnetic resonance benzimidazole
