Abstract
The research relates to developing a process for making fatty acid-based surfactants from renewable natural resources. At this stage, the potential of stearic acid and lauric acid to be synthesized into fatty amide surfactants was observed using monoethanolamine and urea as an amine source. In this study, the potential utilization of two types of fatty acids, namely lauric acid and stearic acid, was reacted with monoethanolamine using CaO and hexane-isopropanol solvent in a stirred tank reactor. For this reason, the research was planned to study the effect of reaction time, stirring speed, and temperature on the amide recovery. The success of the process is measured by the best conversion of fatty acids produced, as well as observing the effect of the three reaction variables on the conversion of fatty acids. Furthermore, structural tests were carried out with FT-IR spectroscopy. As a result, the lauric acid conversion was 83.33%, and the stearic acid conversion was 82.38%, obtained at a substrate (fatty acid: MEA) ratio of 1:8, a catalyst weight of 5%, and a solvent ratio of 2:1.
