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 assess their physical properties and to obtain a thermochemical profile. The experiment as described here could be employed by university faculty as a project in a major’s level laboratory course, but we envision the ideal fit to be a module within an advanced or integrated laboratory course. Students completing the project gain valuable experience in chemical synthesis and in extensive product characterization and analysis. This project reinforces critical skills in isolation of pure products from complex mixtures and in the careful preparation of samples for chemical analysis. Finally, students are afforded the opportunity to compare theoretical predictions from chemical modeling in combination with GC–MS analysis with the practical results gained by performing bomb calorimetry.

生物柴油，柴油，煤油和喷气燃料的燃料成分和物理性质的比较分析

生物柴油是通过植物油，动物脂肪和再生油脂的酯交换反应合成的重要替代燃料。在该实验中，学生通过几种植物油的碱催化酯交换反应制备了生物柴油，随后将其与常规石油基燃料进行对比分析，以评估其物理性质并获得热化学特征。此处描述的实验可以由大学教师作为专业水平的实验室课程中的一个项目使用，但我们认为理想的选择是成为高级或集成实验室课程中的模块。完成该项目的学生将获得化学合成以及广泛的产品表征和分析方面的宝贵经验。该项目加强了从复杂混合物中分离纯产品以及精心准备用于化学分析的样品的关键技能。最后，学生有机会将化学建模与GC-MS分析相结合的理论预测与通过炸弹量热法获得的实际结果进行比较。
