Abstract

The transesterification reaction of Malunggay (Moringa oleifera Lamk) seed oil by means of ethanol, using potassium hydroxide as catalyst, was studied. The objectives of the work were to determine the effect of varying oil-to-ethanol molar ratio (1:9, 1:10, and 1:11) on the volumetric yield, to determine the effect of varying oil-to-catalyst molar ratio (1:0.1, 1:0.2, and 1:0.3) on the volumetric yield, to establish a reaction time profile of the transesterification reaction using the selected favorable oil-to-ethanol-to-catalyst molar ratio, and to quantify the ethyl ester content of the final product by using Thin Layer Chromatography (TLC) and by Quantiscan analysis. All runs were done at room temperature. Results showed that 1:11 was the most favorable oil-to-ethanol molar ratio with the highest volumetric yield of 88% and 1:0.3 was the favorable oil-to-catalyst molar ratio with the highest volumetric yield of 87.5%. It means that increasing the ethanol and potassium hydroxide amounts both increased the volumetric yield. Results of the TLC and Quantiscan using the most favorable oil-to-ethanol-to-catalyst molar ratio of 1:11:0.3 showed that almost 99% of ethyl ester was produced in a 4-hour reaction time. However, sufficient percentage (97.87%) of ethyl ester was already achieved after 3.2 hours.
