1-(2-Aminoethyl)-1-dodecyl-2-undecyl-4,5-dihydro-1H-imidazol-1-ium chloride, 1-(2-Aminoethyl)-1-dodecyl-2-tridecyl-4,5-dihydro-1H-imidazol-1-ium chloride as Corrosion Inhibitors for Carbon Steel in Oil Wells Formation Water



Abstract Introducing1-(2-aminoethyl)-1-dodecyl-2-undecyl-4,5-dihydro-1H-imidazol-1-ium chloride (LQI), 1-(2-aminoethyl)-1-dodecyl-2-tridecyl-4,5-dihydro-1H-imidazol-1-ium chloride (MQI) as two organic structures quaternary ammonium salts, which have been made and analyzed by FTIR, 1H NMR spectroscopic methods. (X-65) carbon steel’s corrosion in naturally formed rocks’ oil wells formation water in the nonappearance (Blank) and using a wide range of concentrations (50, 100, 200, 300, 400, 500 ppm) of these cationic surfactants, as inhibition blockers using direct current (DC), alternative current (AC) electrochemical ways. To sum up, the inhibition efficiency grew with up the gradual rise in the inhibitor content till having peaked at (500 ppm) registered (94.83%) for (MQI). Specifically, carbon steel’s morphology was closely inspected with the aid of highly automated scanning electron microscopy, and energy dispersive X-ray facilities. As a matter of fact, quantum chemical calculations enriched the theoretical study of the (LQI, MQI) compounds depend on energy levels’, energy maps, and 3D structures consideration.
