Using bioethanol for biodiesel synthesis it is possible to obtain a 100% renewable product [1]. Although at present ethanol is more expensive than methanol, it presents many advantages [1-3]. Among the basic homogeneous catalysts used for biodiesel production, the one with best performance so far is sodium methoxide. Therefore, if the objective is obtaining biodiesel entirely composed by ethyl esters, the methoxide catalyst must be replaced. In this work, the transesterification reaction was performed using ethanol as alcohol and sodium ethoxide as catalyst.
