Abstract
An integrated gas chromatography—Fourier transform infrared spectroscopy—mass spectrometry system was utilized in the analysis of a neutral and acidic fraction obtained from the aqueous portion of the low-severity coal liquefaction products. Reconstructed selected-ion chromatograms along with reconstructed absorbance chromatograms over elected ranges were useful in discriminating between the types of organic compounds in the complex mixtures. A series of γ-lactones and a series of ketones were characterized, the ring size and unsaturation being determined by the absorbance frequency of the carbonyl stretching band.
