| 摘要 |
The invention relates to a process for preparing alkyl esters of fatty acids having the general formula (I) and acrolein by reaction of triglycerides of the general formula (II), characterized in that a) the triglycerides are reacted with alcohols R'-OH in the presence of a suitable catalyst to form the alkyl ester of a fatty acid and glycerol and b) the glycerol formed is dehydrated catalytically to form acrolein, b) where R is R1, R2 and R3 and R1, R2 and R3 are all identical or partly identical or all different and are each a straight-chain or branched C10-C30-alkyl radical which may be saturated, monounsaturated or polyunsaturated and R' is a C1-C10-alkyl radical or a C3-C6-cycloalkyl radical. |
