Synthesis of Biodiesel
In this experiment, biodiesel was synthesized from canola oil using sodium methoxide as a catalyst. The procedure involved dissolving sodium hydroxide in methanol, then heating canola oil in a round-bottom flask while stirring. The sodium methoxide solution was slowly added to the oil, and the reaction was maintained under reflux for a period of time. After cooling, the mixture was transferred to a separation funnel, where the layers were allowed to separate. The lower phase was removed, and a few droplets of hydrochloric acid were added to neutralize the biodiesel layer. Washing with water was performed to ensure the pH was around neutral.
For viscosity analysis, the relative viscosity of the biodiesel compared to the original canola oil was determined using a pipette.
