Elucidation of corrosion inhibition property of compounds isolated from Butanolic Date Palm Leaves extract for low carbon steel in 15% HCl solution
Abstract
<p>The present work reports on the corrosion inhibition property of compounds isolated from butanolic extract of Date Palm leaves for low carbon steel in 15% HCl solution. Six compounds were isolated from Date Palm leaves and purified using a combination of column chromatography, thin layer chromatography, and Prep HPLC-MS system. The isolated compounds were characterized using <sup>1</sup>H NMR, <sup>13</sup>C NMR, and GC–MS. Their identity was revealed to be a mixture of fatty alkanes, oleanolic acid (OA), vanillyl alcohol (VA), β-Sitosterol-3-O-β-D-glucoside (β-SSG), sucrose sugar, and carotenoid lutein. As a result of the amount of the different isolates obtained, only three out of the six compounds namely β-SSG, OA, and VA were tested for anticorrosion property for low carbon steel in 15% HCl. The corrosion inhibition of the isolated compounds was performed using weight loss and electrochemical techniques. Surface morphology analysis of the corroded steel in the absence and presence of the isolated compounds was undertaken using SEM/EDAX and 3D optical profilometer. Also, DFT calculations was performed in order to indicate the reactivities and bonding sites of the isolated molecules as well as Monte Carlos simulations (MCS) to determine the energy of interaction between the inhibitors and carbon steel surface. Results obtained show that the values of inhibition efficiency (IE) for the different isolated compounds at the concentration (35 ppm) studied follow the trend: β-SSG (46.57%) > VA<sub>isolated</sub> (39.30%) > VA<sub>commercial</sub> (36.81%) > OA (31.94%) at 25 °C. It is also noted that, for the isolated OA, IE increased with increase in concentration but decreased with increase in temperature. For isolated VA, IE decreased with increase in temperature. However, for the commercial VA, IE slightly increased with rise in temperature. The experimental results are in agreement with the theoretical prediction. In both predicted and experimental results, β-SSG is the best corrosion inhibitor.</p>
