Abstract

The invention provides methods of synthesizing and purifying methyl esters and specifically biodiesel fuels. The methods include acid-catalyzed transesterification of a triglyceride source followed by formation of an acidic emulsion that is subjected to an electric field to break the emulsion and recover the purified methyl esters. After recovery, the purified methyl esters may be used as a highly purified and stable biodiesel fuel without further treatment. The electric field may be efficiently applied to the acidic emulsion in an electrochemical reactor such as an electrocoagulation chamber.
