Pyridine has been selected as the solvent of choice for extraction of the soluble portion of coal. All extractions and subsequent treatments of the coal and coal extracts must be done under conditions that ensure that the samples are never exposed to temperatures above approximately 200 deg C. Treatments at higher temperatures have produced thermal degradation of the coal molecules. The volatile fraction of the pyridine extracts of two coals (PSOC-521 and PSOC-592) have been fractionated into chemical classes and analyzed by capillary gas chromatography-mass spectrometry. Major compounds were identified as pentacyclic triterpanes, (hopanes and moretanes), alkylated 2- and 3-ring polycyclic aromatic compounds, and unsaturated pentacyclic triterpane derivatives. Five new compounds, never before reported, have been identified. A new UV-absorbance detector cell has been constructed for evaluation of different supercritical mobile phases and mobile phase additives. Preliminary experiments with supercritical ammonia indicate that this polar fluid may be useful for chromatography of coal molecules.
