The utility of liquid SO/sub 2/ for the removal of organic sulfur from several Eastern bituminous coals has been explored. Reactions were carried out in sealed fritted glass tubes at elevated temperatures; after subsequent washing, the coal was analyzed for sulfur content. Approximately 40% of the organic sulfur could be removed in these simple exploratory experiments. In addition, comminution of most of the coals occurred and a portion of the coal was extracted. The extract from selected coals was characterized by thin-layer chromatography, by nmr (/sup 1/H and /sup 13/C) and infrared spectroscopy, and by field-ionization mass spectrometry. For comparison, extractions with phenol and p-cresol, under similar conditions, were also examined. The results of these preliminary investigations warrant further research to establish optimum conditions for the removal of sulfur compounds from coal by treatment with liquid SO/sub 2/ and to facilitate removal of residual SO/sub 2/ from the coal.
