Mixed alkoxide catalyst for biodiesel production

Abstract

A process for producing fatty acid C1-C4-alkyl esters, useful as biofuel. from an organic oil source is provided, wherein the oil source contains a triglyceride and a free fatty acid in an amount of at least 0.1 wt %, based on the total weight of the organic oil source. the process comprising a) reacting the organic oil source with a C1-C4-alkanol in the presence of an alkaline catalyst to form an ester phase and a glycerol phase: and b) isolating the fatty acid C1-C4-alkyl esters from the ester phase: wherein the alkaline catalyst is a mixture of metal alkoxides.
