The Production and Characterization of Biodiesel

The focus of this project is on making and characterization of biodiesel synthesized from vegetable oil. Students will use corn oil to carry out a saponification reaction. Prior to this reaction, students will titrate the oil to determine the correct amount of base for the conversion to biodiesel; too much base will result in the formation of soap. Students will characterize the biodiesel by IR and gas chromatography/mass spectrometry (GC/MS). Students will also use bomb calorimetry to determine the heat of combustion of the biodiesel produced. The goals of this project are: (1) to understand the composition of vegetable oils; (2) to understand how biodiesel is produced; (3) to learn how to saponify an oil; (4) to learn how to do an acid/base titration; (5) to understand thermochemistry in order to carry out a bomb calorimetry experiment (6) evaluate the quality of biodiesel by comparing to commercial diesel products (7) to understand IR and how GC/MS can be used to characterize a reaction mixture.
