Preparation and Combustion of Biodiesel. An Inquiry-Based Chemistry Laboratory

In this lesson, the students develop a synthesis to make biodiesel from vegetable oils. Students convert canola oil, a common vegetable oil found in kitchen, to biodiesel. The conversion involves a transesterification reaction of a triglyceride with methanol to produce biodiesel and glycerol. In addition to working in a synthesis laboratory, the students get the chance to compare biodiesel with petroleum-based diesel in environmental, energy source considerations. The biodiesel is compared with diesel from petroleum industry by the heat of combustion. We are interested in finding environmentally friendly alternatives to replace the traditional petroleum fuels. Biodiesel is green and renewable. Renewable biofuels reduce dependence on imported oil and reduce the carbon footprint.
