Biodiesel from uncommon fatty acids

Abstract

Ethyl esters from uncommon fatty acids, such as valproic, azelaic, and sorbic acids, were chemically synthesized and identified by gas chromatography or liquid chromatography coupled to mass spectrometry. Some properties were evaluated to determine their potential for use as biofuels or in other commercial applications. They have remarkable and pleasant odors and, in the case of ethyl ester in valproic acid, display marked resistance to clouding and crystallization.
