). The preparation of fatty acid methyl esters for glc analyses and of various aryl esters for hplc analyses has traditionally been carried out in totally unrelated operations. This paper draws attention to the use offatty acid -trifluoroacetic acid mixed anhydrides which may be directly and efficiently converted into either type of ester. The utility of the method was demonstrated by the preparation of a series of methyl, 2-naphthyl, and vanillin fatty acid esters. The spectral characterization of some aryl fatty acid esters is recorded. [Traduit par le journal]
Für chromatographische Untersuchungen werden die Fettsäureester (V) synthetisiert; die Synthese erfolgt durch Umsetzen der Fettsäuren (I) mit dem Anhydrid (II) zu den gemischten Anhydrideh (III) und deren Behandlung in dem Reaktionsmedium mit den Alkoholen (IV).
