Influence of the synthesis process on the properties of flow and oxidative stability of biodiesel from Jatropha curcas biodiesel

► Biodiesel obtained with Jatrophacurcas, through ethanol route, basic catalysis. ► Importance of time span after ethoxide preparation on biodiesel properties. ► Washing water volume diminishes with time span. ► Best results for flow properties and yield for intermediary time span. ► Best oxidative stability for highest time span.
