Abstract
AbstractIn this paper, the inhibition performance of a novel dissymmetric bis‐quaternary ammonium salt with an imidazoline ring and an ester group (DBAS) for Q235 steel in 2 % NaCl solution saturated with CO2 was investigated using weight loss, the polarization curve, electrochemical impedance spectroscopy methods and the quantum chemistry calculation. The results show that DBAS, which is good for the environment and have many activated centers and low ELUMO, has a high inhibition performance for Q235 steel in 2 % NaCl solution saturated with CO2. The inhibition efficiency of the studied corrosion inhibitor increased with increasing inhibitor concentrations. The inhibitor is a mixed‐type inhibitor which inhibits both anodic and cathodic reactions.
