Green chemistry principles in the organic teaching laboratory: an environmentally benign synthesis of banana oil and aspirin

Abstract

This study explores how undergraduate organic chemistry courses may incorporate green chemistry concepts. It gives a summary of the findings and explains the rationale for integrating ecologically friendly practices into education. The article aims to demonstrate the possible benefits of incorporating green chemistry topics at the fundamental level of organic chemistry instruction by examining teaching strategies and providing case studies. Emphasis is placed on the transformative impact of integration on student learning and the broader environmental landscape that promotes a more sustainable and environmentally friendly approach to chemistry education. The article includes examples of laboratory exercises, featuring the application of green chemistry concepts in the synthesis of banana oil and acetylsalicylic acid. Through these experimental works, students' theoretical knowledge of stereochemistry, reaction processes, and the synthesis and analysis of organic molecules are strengthened. In particular, the aspirin and isoamyl acetate synthesis helps explain the processes of the esterification and acetylation reactions. Additionally, by demonstrating essential techniques like extraction, reflux, and recrystallization, these types of experiments help undergraduate students become more proficient in the lab.
