Abstract
In the present work, the compound 3´-(2,6-dimethoxybenzoyl)-benzyl 2,6-dimethoxybenzoate (RM4) was evaluated for its ability as a corrosion inhibitor in a 3% chloride medium and using an API 5L X70 steel working electrode. The electrochemical system was evaluated by electrochemical techniques such as polarization curves (CP) and electrochemical impedance spectroscopy (EIS), finding through the values obtained in polarization curves that the efficiency of the inhibitor at 50 ppm reached 73.2% against the corrosion phenomenon. The inhibition kinetics study shows that the evaluated organic compound maintains its protection against corrosion in a period of 120 hours of immersion.
