VERFAHREN ZUR HERSTELLUNG VON FETTSÄUREALKYLESTERN UND ACROLEIN AUS TRIGLYCERIDEN

摘要

A fatty acid alkyl ester of the general formula I: and acrolein are prepared by reacting a triglyceride of the general formula II: wherein a) the triglyceride is reacted using an alcohol R'-OH in the presence of a catalyst to give said fatty acid alkyl ester and glycerol; and b) the glycerol is dehydrated catalytically to acrolein, wherein R is R1, R2 and R3, and R1, R2 and R3 are all the same or some are the same or all are different and are each a straight-chain or branched, and optionally mono- or polyunsaturated C10-C30-alkyl radical, and R' is a C1-C10-alkyl radical or a C3-C6-cycloalkyl radical.
