The objective was to evaluate the yield of biodiesel production from used soybean oil for a better use of used oils by the transesterification method, Calcium Oxide (2 and 6%) and the Molar Ratio of ethanol were evaluated: oil (9:1 and 15:1). A 22 factorial experimental design with five central points was proposed to evaluate the effect of the ethanol:oil molar ratio parameters and the percentage of Calcium Oxide concentration on biodiesel yield. The highest biodiesel yield was 60.9%, with a 15: 1 ethanol:oil molar ratio and a 6% calcium oxide concentration. It should be noted that this performance could be optimized by applying the response
surface methodology, the viscosity was 8.70 centistokes, a result that was close to the ASTM D6751-09 standard. Finally, the control variables with molar ratios greater than 15:1 and catalyst concentrations close to 6% are applicable to optimize the yield of biodiesel production.
