dos Anjos, Rodrigo; Silva, Márcio Santos – Journal of Chemical Education, 2020
Biodiesel is an important biomass, largely employed in the transport sector and produced from vegetable oils. Additionally, waste cooking oils may be reused to produce biodiesel fuel, minimizing environmental pollution. A laboratory experiment that affords a widespread way to discuss degradation concepts and tools for used vegetable oil…

Delgado, Sergio Nogales; Martín, José María Encinar; Suero, Silvia Román – Journal of Chemical Education, 2021
One of the most general aims of universities is to respond to the requirements of society. Health and safety are the most important aspects of professional work and play an important role in universities, as there, future professionals are trained for their future professional life. Scientific and technical degrees require adaptation to this…

Knoerzer, Timm A.; Hill, Elise M.; Davis, Todd A.; Iacono, Scott T.; Johnson, Jane E.; Balaich, Gary J. – Journal of Chemical Education, 2018
Biodiesel is an important alternative fuel synthesized by the trans-esterification of vegetable oils, animal fats, and recycled greases. In this experiment, students prepared biodiesel through the base-catalyzed trans-esterification of several vegetable oils, which were subsequently analyzed in comparison with conventional petroleum-based fuels to…

Leibfarth, Frank A.; Russell, M. Grace; Langley, David M.; Seo, Hyowon; Kelly, Liam P.; Carney, Daniel W.; Sello, Jason K.; Jamison, Timothy F. – Journal of Chemical Education, 2018
This laboratory experiment leverages the pedagogical value and multidisciplinary nature of biodiesel production from vegetable oil to introduce students to continuous-flow chemistry, a modern and rapidly growing approach to chemical synthesis. An interdisciplinary approach exposes students to the practical and conceptual aspects of modern…

Nida, Safwatun; Marsuki, Muhammad Fajar; Eilks, Ingo – Journal of Chemical Education, 2021
This paper presents a case study examining the current controversial issue of palm oil production for manufacturing biodiesel in Indonesia. The study looks at how this issue was used as a context to teach chemistry at the undergraduate level. The lesson unit promotes general educational skills, which students need to develop in order to become…

De La Rosa, Paul; Azurin, Katherine A.; Page, Michael F. Z. – Journal of Chemical Education, 2014
This laboratory investigation challenges students to synthesize, analyze, and compare viable alternative fuels to Diesel No. 2 using a renewable resource, as well as readily available reagents and supplies. During the experiment, students synthesized biodiesel from soybean oil in an average percent yield of 83.8 ± 6.3%. They then prepared fuel…

Goldstein, Steven W. – Journal of Chemical Education, 2014
Plants can store the chemical energy required by their developing offspring in the form of triglycerides. These lipids can be isolated from seeds and then converted into biodiesel through a transesterification reaction. This second-year undergraduate organic chemistry laboratory experiment exemplifies the conversion of an agricultural energy…

Cavalcante dos Santos, Rafael; Cavalcanti, Juliane Natalizi Cabral; Werneck do Carmo, Elisa Carneiro; de Souza, Fernando Costa; Soares, Wesley Garcia; de Souza, Cristiane Gimenes; de Andrade, Débora França; d'Avila, Luiz Antonio – Journal of Chemical Education, 2020
An experimental procedure is presented that was developed by fifth-year chemical engineering and industrial chemistry undergraduates at the Federal University of Rio de Janeiro doing the discipline on Experimental Organic Technology. The aim of this study was to apply the solvatochromic effect of the dye Nile Blue chloride to the characterization…

Daconta, Lisa V.; Minger, Timothy; Nedelkova, Valentina; Zikopoulos, John N. – Journal of Chemical Education, 2015
A new, general approach to the organic chemistry laboratory is introduced that is based on learning about organic chemistry techniques and research methods by exploring the natural products found in local native plants. As an example of this approach for the Sonoran desert region, the extraction of jojoba oil and its transesterification to…

Bendall, Sophie; Birdsall-Wilson, Max; Jenkins, Rhodri; Chew, Y. M. John; Chuck, Christopher J. – Journal of Chemical Education, 2015
Chemical engineering is rarely encountered before higher-level education in the U.S. or in Europe, leaving prospective students unaware of what an applied chemistry or chemical engineering degree entails. In this lab experiment, we report the implementation of a three-day course to showcase chemical engineering principles for 16-17 year olds…

Heasley, Paul L.; Van Der Sluys, William G. – Science Teacher, 2009
Through a collaborative project in Pennsylvania, high school students developed a method for converting batches of their cafeteria's waste fryer oil into biodiesel using a 190 L (50 gal) reactor. While the biodiesel is used to supplement the school district's heating and transportation energy needs, the byproduct--glycerol--is used to make hand…

Pohl, Nicola L. B.; Streff, Jennifer M.; Brokman, Steve – Journal of Chemical Education, 2012
Herein we describe a series of experiments for the undergraduate organic laboratory curriculum in which various plant oils (soybean, rapeseed, and olive) are subjected to saponification and transesterification reactions to create a set of compounds that can function as soaps or as fuels. The experiments introduce students to and asks them to…
