Abstract
Microwave-assisted and conventional heating methods were evaluated in the transesterification acid-catalyzed reaction of vegetable oil with methanol into the methyl ester using a variety of solid acid catalysts, p-toluenesulfonic acid and Nafion NR 50 and the liquid catalyst sulfuric acid. Both heating methods gave excellent yields of product (<85%); however the microwave-assisted synthesis was completed in shorter reaction times, 1 h compared to more than 24 h. The heats of combustion for the biodiesel product were found to be between 38.75 and 42.05kJ/g, similar to literature values; however they are lower than the heat of combustion value for commercial petroleum diesel of 45.52kJ/g.
