不饱和脂肪酸的酰胺类化合物给出的质谱表明了双键的位置。对几种油酸酰胺进行了考察，以评价哪一种酰胺最适合用于常规的结构分析。用质谱和气相色谱资料介绍了几种油酸酰胺的制备方法。叔酰胺具有最容易解释的质量谱图，它表示脂肪酸链中双键的位置。吡啶烷在脂肪酸气相液相色谱和质谱分析中具有优势，因为它易于在微观尺度上以高收率制备，气相液相色谱分离时具有足够的挥发性，并且具有简单且易于解释的质谱，可以显示其结构。
Amides of unsaturated fatty acids give mass spectra which indicate the locations of the double bonds. A survey of several amides of oleic acid was made to evaluate which amide might be most suitable for routine use in elucidation of structure. Methods of preparation of several amides of oleic acid are presented with mass spectral and gas chromatographic data. Tertiary amides have most easily interpretable mass psectra which indicate the position of the double bond in the fatty acid chain. The pyrrolidide is advantageous for fatty acid gas liquid chromatography and mass spectrometry analyses because it can be prepared easily in high yield on a microscale, it is volatile enough for gas liquid chromatographic separations, and it has a simple and easily interpretable mass spectrum which indicates the structure.
