Abstract

New corrosion compounds were prepared based on acryloyl chloride and the efficiency of the prepared compounds to inhibit carbon steel (CS) corrosion in 3.5% sodium chloride solution were studied through different electrochemical techniques [potentiodynamic polarization (PP), electrochemical impedance spectroscopy (EIS) and electron frequency modulation (EFM)] and Quantum chemical calculations. The results showed that the investigated compounds are working as good corrosion inhibitor compounds, the inhibition efficiency (%IE) increases as the compound concentration increase. The polarization data revealed that these compounds act as cathodic and mixed type compounds and are adsorbed on CS surface following Langmuir adsorption isotherm.
