The present investigation evaluates the production process of biodiesel of canola oil, by means of the homogenous basic transesterification method, where potassium hydroxide KOH (0.9% m / m) is used, and processed with methanol as a catalyst (20% v/v), aided by mechanical agitation, and the direct ultrasonic irradiation method with the same proportions of methanol and catalyst. Commercial canola oil was used in the reaction at 65 ° C, this was mixed with methoxide (mixture of methanol and potassium hydroxide catalyst) with agitation times; for 15, 30, 45 and 60 minutes, for the ultrasonic agitation method, a frequency of 20 kHz and amplitude of 30 percent was used with a mechanical agitation time of 120 minutes and heat at 300 rpm. For both methods of biodiesel production, basic quality control parameters were used, such as methyl esters content that measured the yield of the reaction, where it was obtained acceptable values of 84% in its production when working at 45 minutes with ultrasonic irradiation, compared to 86.9% obtained by the conventional method. In addition, it was identified qualitative the methyl esters produced using infrared spectroscopy and gas chromatography. Finally, the metrics or sustainable factors in green chemistry were used to show that the process with ultrasonic irradiation generates major environmental benefits.
