| Summary: | Over a century of studies of the organic chemistry of coal has led to many accomplishments in coal chemistry. The recognition of the role that sulfur plays in coal makes the speciation of sulfur in coal one of the most important research goals. In this research solvent extraction, ultimate analysis, FTIR, TG-FTIR, sulfur methylation, and NMR techniques were employed to make quantitative and qualitative determinations of the organic sulfur in coal and its extracts. The data obtained from those methods are discussed with regard to the analytical and synthetic approaches used. Carbon-sulfur bond cleavage at room temperature was observed during this research and was verified using reactions of model compounds. |
