Biodiesel is a readily produced and commonly used alternative fuel source. Biodiesel can be synthesized from renewable resources, such as used cooking oil, through esterification of free fatty acids (FFA) or tranesterification of triglycerides. Because used oils are often contaminated with FFA's we have chosen oleic acid as a model system for investigating reactions that convert FFA into methyl esters. An acid catalyst is used to treat the FFA's and create fatty acid methyl esters (FAME). Tin halides are common Lewis acid catalysts and are readily available. Preliminary results show that the rate constants for these reactions fit the following trend: SnF2 < SnCl2 < SnBr2 < SnI2, monitoring the reaction progress using 1H NMR. Based on these results, we have undertaken a series of experiments to determine the activation energies of the reactions. This poster will present my methods and results on the use of tin (II) iodide to catalyze the methylation of oleic acid.
