説明

<jats:title>Abstract</jats:title><jats:p>Trimethylsilylation has proved to be extremely useful in the gas chromatography and the mass spectrometry of hydroxy acid methyl esters. The characteristic mass spectral fragmentation patterns have shown these derivatives to be superior in some respects to others for structural elucidation; in particular, hydroxylation followed by trimethylsilylation provides a useful method of double bond location in unsaturated fatty acid esters.<jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#note1"/><jats:fn><jats:p>A preliminary presentation of this method has been given by G. Eglinton at the Lecture etting in <jats:italic>Combined Gas Chromatography—Mass Spectrometry</jats:italic> at the school of Pharmacy, London, August 9, 1967. It has come to the authors' attention that this method simultaneously developed by Dr. P. Capella, Institute di Industria Agrarie, University of Bologna, Italy<jats:sup>1c</jats:sup> (P.
