The asymmetric bis quaternary ammonium salt containing imidazole ring was synthesised suc-cessfully. And weight-loss method,electrochemical impedance spectroscopy,potentiodynamic polarization curve,scanning electron microscopy was used to study on the inhibition efficiency of this product in sodi-um chloride solutions(3. 00%)bubbled with CO2-saturated. The result shows that it has good corrosion inhibition for the P110 steel in this solution,and the corrosion inhibition efficiency is closed to 90%. The adsorption behavior was fitted using the Langmuir adsorption isotherm,and showed that the adsorption type conforms to the Langmuir adsorption isotherm,its adsorption mode is chemical adsorption.
