The effect of ultrasonic irradiation energy was analyzed according to the kinds of alcohol in the ultrasonic alcoholysis. The ultrasonic irradiation energy density of ethanol (792.9 kJ/L) is higher than methanol (649.8 kJ/L). The optimum mixing ratio of canola oil, methanol and ethanol was proven as 1, 5 and 1, respectively. Also the optimum reaction conditions for the ultrasonic alcoholysis were a reaction temperature of 60 ℃, ultrasonic irradiation power of 500 W, reaction time of 50 min, and alkaline catalyst (KOH) content of 0.6 wt.%. From these results, the optimum alcohol mixing ratio and the optimum process conditions were determined, with good quality biodiesel being manufactured.
