9.2 The Reaction of Biodiesel: Transesterification | EGEE 439
9.2 The Reaction of Biodiesel: Transesterification. So, how do we make biodiesel? The method being described here is for making FAMEs biodiesel. The reaction is called transesterification, and the process takes place in four steps. The first step is to mix the alcohol for reaction with the catalyst, typically a strong base such as NaOH or KOH.

As shown in the diagram, Pimentel and Patzek calculate that 7,800,000 kcal of energy is required to grow 5,556 kg of soybeans. As is usual practice in these energy balance studies, solar energy inputs are not included in this total so processes may actually appear to be creating energy rather than simply converting it from one form to another.
