Bladt, Don; Murray, Steve; Gitch, Brittany; Trout, Haylee; Liberko, Charles – Journal of Chemical Education, 2011
This undergraduate organic laboratory exercise involves the sulfuric acid-catalyzed conversion of waste vegetable oil into biodiesel. The acid-catalyzed method, although inherently slower than the base-catalyzed methods, does not suffer from the loss of product or the creation of emulsion producing soap that plagues the base-catalyzed methods when…
