The synthesis of Aspirin and Acetobromo-α-D-glucose using 3D printed flow reactors: an undergraduate demonstration

The field of flow chemistry is growing rapidly, drawing attention across different disciplines. Despite its increasing popularity in the industry and research, little attention is given to the teaching of flow chemistry in the educational environment, especially at the undergraduate level. A major challenge with teaching undergraduate flow chemistry is the high cost of flow chemistry equipment. This study reports the development of low-cost, functioning flow chemistry equipment for the teaching of flow chemistry and experimental practicum. This provides the students with hands-on instruction in fabricating flow reaction devices by 3D printing. It also allows undergraduate students to understand the basics of flow chemistry and chemical engineering. An exciting part of this study is the skills acquired by undergraduate students. This is because of the learning experience they are exposed to by training and independently operating fabrication equipment, setting up flow experiments and conducting flow experiments with the fabricated devices. Finally, due to the low cost of the equipment, the set-up is suitable for teaching flow chemistry in a low-resource environment, such as our teaching laboratories in South Africa.

Automated summary

The field of flow chemistry is gaining attention across different disciplines, however, there is little focus on teaching flow chemistry, especially at the undergraduate level. This study presents the development of low-cost flow chemistry equipment for educational purposes, allowing students to fabricate flow reaction devices through 3D printing and gain hands-on experience in flow chemistry and chemical engineering. The skills acquired by undergraduate students through this study are an exciting aspect, as they learn to operate fabrication equipment, set up flow experiments, and conduct experiments with the fabricated devices.
