Abstract

This study was carried out as an attempt to convert methyl esters coconut oil into nitrogen compounds by reacting the methyl esters with diethanolamine. Three samples were prepared by carrying out experiment at 80°C for 24 h, at 100°C for 24 and 48 h. The products of the reactions were analyzed using GC-MS and then utilized as corrosion inhibitor for mild steel in CO2 saturated brine solution using Wheel test method. The inhibition activity of the samples was evaluated in terms of percentage protection and surface morphology of the sample using SEMEDX method. The experimental results obtained revealed that the experiments conducted at 80°C for 24 h and at 100°C for 24 h only produced nitrogen compounds as a minor component, but in the sample produced from the experiment carried out 100°C for 48 h a series of nitrogen compounds were produced, contributing 53.54% to the composition. The results of corrosion testing experiments revealed that the samples exhibit corrosion inhibition activity, with the highest protection of 97.9% was provided by the sample prepared at 100°C for 48 h. Without ignoring the need for further research, the results obtained in this study suggest that the nitrogen compounds derived from coconut oil possess promising potential as green corrosion inhibitor.
