✦ Synopsis

An integrated gas chromatography Fourier transform infrared spectroscopymass 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 y-lactones and a series of ketones were characterized, the ring size and unsatura .tion being determined by the absorbance frequency of the carbonyl stretching band,

Flash-pyrolyses of two furfuraldehyde resins were performed at 980 and 770 °. The identities of volatile products were established by employing two coupled systems, viz. pyrolysis(gas chromatography)-(mass spectrometry) in electron-impact and chemical-ionization modes and pyrolysis(gas chromatograph
