摘要：

Characterization of components in the acid and base fractions of shaie oil has been achieved by means of selective extraction followed by gas chromatographic separation of individual phenolic and heterocyclic nitrogen base compounds on a stainless steel porous layer open tubular, free fatty acid phase column. Interfaced rapid scan vapor phase infrared spectrophotometry (VPIR) allowed informative spectra to be obtained for microgram component peaks, computer data handling giving improved measurement sensitivity. Qualitative identification of substituted phenolics and pyridine bases was achieved by coordination of retention data, VPIR, and mass spectral data. © 1979, American Chemical Society.
