Microwaves have been employed in this work as a well-proven method to activate the transesterification reaction of triglycerides with methyl esters using heterogeneous catalysts.
The reactions have been carried out with different heterogeneous catalysts, by studying the progression of the reaction time, the effect of the oil-methyl ester molar ratio and the catalyst amount.
Reactions have also been carried out with traditional heating to allow comparison with microwave effects.
