摘要：1,5-Benzodiazepine derivative namely, 4Z-(2-Oxopropyl)-1,3-bis(prop-2-yn-1-yl)-2,3,4,5-tetrahydro-1,5-benzodiazepin-2-one (BZD-1) has been evaluated as corrosion inhibitor for carbon steel in 1M HCl acid by electrochemical impedance spectroscopy (EIS) and potentiodynamic curves techniques. The obtained results showed that BZD-1 is an efficient corrosion inhibitor and an inhibition efficiency of 97% was reached with 1×10-3 M of BZD-1. The protection efficiency increased with increasing inhibitor concentration, but the temperature has significantly effect on the inhibition efficiency of BZD-1. Tafel polarization studies revealed that BZD-1 is mixed type inhibitor. The adsorption of BZD-1 on the surface of carbon steel obeyed the Langmuir adsorption isotherm. The adsorption behavior of the BZD-1 on Fe (110) surface was investigated by Monte Carlo simulations to verify its corrosion inhibition steel efficacy. The adsorption energy between inhibitor and carbon steel has been calculated by Monte Carlo simulations.
