Four new bis-glucobenzimidazolone derivatives have been synthesized and characterized by NMR spectroscopic. They have been tested as corrosion inhibitor for mild steel in 200 ppm NaCl solution using weight loss, potentiodynamic polarization curves and electrochemical impedance spectroscopy measurements. Potentiodynamic polarization curves showed that these compounds were a mixed-type inhibitors. Their inhibition efficiencies improve with concentration and reached a maximum at 10-5 M of each compounds and the 24b is the better. Electrochemical impedance spectroscopy measurements showed that...
