Inhibition of carbon steel corrosion in acidic media by "2-(4-methoxyphenoxy) benzylamine HCl" with several inhibitors' concentrations and temperatures.

This study involved the using of "2-(4-methoxyphenoxy) benzylamine HCl" in order to prevention of carbon steel corrosion in acidic medium. Weight loss and hydrogen gas evolution methods were utilized. Inhibitor concentrations ranging from 50-250 ppm at temperatures ranging from 40-60 °C were used in the current research. The presence of the amine molecules, as well as the oxygen and nitrogen atoms that are important in the adsorption methods, which enhancing the efficiency of inhibition when the inhibitor concentration and temperature are increased. These two approaches demonstrated the inhibitor's efficiency as well as the creation of a layer on the metal's surface via adsorption. The results have been observed that at a temperature of 40 °C and an inhibitor concentration of 250 ppm, the inhibition efficiency was good, and as the temperature increases, the efficiency decreased. Adsorption activation, enthalpy, entropy, and free energy all showed positive findings, with rising activation and enthalpy energy and decreasing entropy energy, suggesting effective adsorption to the inhibitor.
