The Vernier mini GC is a small, affordable instrument for undergraduate laboratories and research. Considering the widespread interest in biodiesel synthesis, we developed a small molecule analogue experiment utilizing triacetin or tributyrin and small alcohol molecules from methanol to propanol. The Vernier mini GC could analyze such small ester products if the sample was prepared by simple distillation of the transesterification mixture. The functional groups could be verified by FTIR. The current experiment used in our organic chemistry curriculum is the fruit of two senior thesis projects and numerous student independent research projects. The development of the experiment with many hard earned caveats will describe a process that deepens understanding of the basic biodiesel synthesis reaction.

Soft baits used in fishing are an amazingly life-like material that has revolutionized fishing world wide. However, there is little that is easily accessible to undergraduate students to understand the chemistry of these materials. Using FTIR to characterize the soft baits and simple melting range analysis to define the heating profile, a kid-safe activity/ demonstration was developed.
