Conversion of Vegetable Oil to Biodiesel Using Ultrasonic Irradiation

Conversion of Vegetable Oil to Biodiesel Using Ultrasonic Irradiation

The influence of low frequency ultrasounds (28 and 40 kHz) versus mechanical stirring on the transesterification reaction of neat vegetable oil with methanol under base-catalysis was studied and the results are presented. It was found that the optimized variables of 6:1 methanol/oil (mol/mol), 0.5%...

description The influence of low frequency ultrasounds (28 and 40 kHz) versus mechanical stirring on the transesterification reaction of neat vegetable oil with methanol under base-catalysis was studied and the results are presented. It was found that the optimized variables of 6:1 methanol/oil (mol/mol), 0.5% NaOH (wt/wt), and 40 kHz ultrasonic irradiation at 25 °C for 20 min gave a maximum isolated ester yield of 98%.
