Abstract
A method for the preparation of fatty acid alkyl esters by transesterification, in particular catalytic transesterification, of triglycerides, wherein from a reaction mixture, in which the transesterification is carried out, an ester phase and a glycerol phase containing fatty acids, fatty acid salts and/or other fatty acid compounds are formed, which are separated from each other, characterized in that the fatty acids, the fatty acid salts and/or other fatty acid compounds are separated from the glycerol phase, esterified with an alcohol and recycled to a different reaction mixture, in which a further transesterification is carried out. The method according to the invention allows for a transesterification with a high yield of fatty acid esters.
