In this module students will learn about Lewis acid-catalyzed synthesis of biodiesel. Students will first perform titrations to determine acid value measurement of waste oil. Students will then carry out Lewis acid catalysis for the transesterification of vegetable oil. Then they will use proton NMR analysis to quantify percent conversion of vegetable oil to biodiesel. Students will repeat the techniques learned while altering a variable of choice each lab with the goal of maximizing the percent conversion to biodiesel.
