Ultrasound-assisted synthesis of biodiesel is a well known process that has been widely used in recent years. A reduction of the processing time and the amount of required catalyst as well as the possibility to work at room temperature have been achieved in most cases. Normally, the use of ultrasound replaces the conventional agitation and heating required to establish close contact between the two...
Ultrasound is considered as one of the most attractive energies to assist biodiesel transesterification. The objective is to reduce the reaction time while saving energy. In the present study, four oils showing a wide range of fatty acid composition have been transesterified using ultrasound as auxiliary energy. Samples included unsaturated fatty acids (rapeseed and soybean) oils and saturated fatty...
