Electrochemical Evaluation of 3´-(2,6-dimethoxybenzoyl)-Benzyl 2,6-Dimethoxybenzoate As a Corrosion Inhibitor in API 5L X70 Immersed in Saline Medium

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